  1. I’m hoping somebody might be able to offer me some advice. I’m a newer fish-keeper that keeps killing any neocaridina shrimp I try to introduce to my tank. I have a 6 month old tank that’s heavily planted. Most of my plants are doing really well. I have some hard scape that shrimp can hide in and a sand substrate. In the tank I have 1 mystery snail and a school of 10 neon tetras that I’ve had no issues with, I only lost one tetra shortly after setting the tank up. They get fed hikari micro pellets and xtreme krill flakes. I have tried to keep neocarinidina shrimp since day one, introducing probably 15-20 to this point. Most of them never survived beyond a month. I had a couple that were first introduced 6 months ago that lasted until this past week, but now they too passed. They’ve been fed algae wafers and hikari shrimp cuisine. The tank is cycled, temperature is good, all parameters that can be tested on the general test strips and a master test kit have always been testing at acceptable levels, so I’m trying to figure out what else could be going wrong? Looking into it some more, I did find that my local tap water has copper in it, so I’m wondering if that could be the cause? Any help would be appreciated.
  2. Hello everyone, I thought I'd share an incredible species of snail I personally own that is local to the country I currently live in (Israel). Meet Theodoxus jordani, this tiny snail is part of the Neritidae family. It behaves exactly like it's larger cousins, is voracious algae eater, looks amazing, and lays tiny little eggs everywhere. There are two main differences between it and a "regular" Nerite: Firstly, it's tiny! This snail reaches a maximum size of 1 cm but most commonly they reach the size of 0.5 cm. Secondly, they breed in freshwater. They lay tiny singular eggs in the aquarium that hatch after about 30 days depending on the temperature. This is what makes them incredible in my eyes. I have breeding groups of them in 4 out of my 6 aquariums. Breeding behavior Size comparison Horrible macro shot of an egg.
  3. Aquariums hold many more living things than fish. What is in your tank? I caught this grass shrimp last week in a ditch while collecting banana plants.
  4. This thread is to document the setup, care and lifetime of my newly created 20 gallon long Walstad deep sandbed tank! I've been planning this project for a while now, and after assuring that the cabinet the tank was destined to sit on was sturdy enough, I took advantage of the latest Petco sale. My husband was a total enabler on this one, which was fun! I've been fascinated by Walstad tanks (and other dirted tanks that use plant-only filtration) since I restarted in this hobby a few years ago, and though all of my other tanks are dirted, none of them have that deep substrate or the no water changes / no filter rule. So this will be a new experience. The planned live stock will be a colony of bloody mary neocaridinas, a vampire shrimp, and perhaps some rabbit snails (among my usual hitchhikers). Edit: It's come to my attention that what I'm doing is slightly different than Diana Walstad's method, but the idea is still the same. After spray painting the back black, I was sure to center the tank and the runner it sits on as best I could. I might have to move that hyena picture above it... it looks off center now! This is the brand of dirt I chose to use. I've never used it before, but I couldn't find the cheapo stuff I used before. I didn't bother sifting the dirt, I just pulled out bigger pieces of wood if I found them. I spread an inch deep layer and pressed it down, and then sprinkled some crushed coral over it, as my water has pretty low Kh. I then sprayed the dirt down with a spray bottle to get it wet, before capping it with two inches of Black Diamond blasting sand - my go to substrate, I like the black color and how cheap it is. I didn't bother washing it, because I'm convinced it doesn't matter. I used a wooden skewer with an inch and three inches both marked off, so I could ensure I had the proper layer depths. Now to fill 'er up! I put a ziplock bag on the sand to soften the water flow. Worked like a charm. As it began to fill, I sorted out the air pump and bubblers. I used Aquarium Co-Op's black airline tubing that they sent me in my care package, and I gotta say it hooks up like butter. Very nice. The bubblers are these fancy ones that came with my Eheim pumps. I wanted lots of flow for the vampire shrimp, so I added two bubblers. Time for hardscape. I'm keeping it simple, and just used some slate pieces I had sitting around. And then it was time for more filling. This time I used a bowl to disperse the water flow. I filled it almost all the way, and then decided it was planting time. I grabbed out a bunch of Val from my 29 gallon. Here's how it looks with the plants in. I do intend to get some moss or maybe Susswassertang. If my new pink flamingo crypt settles in the 75 well I might put some in here too. But for now, I'll let the val fill in The first inhabitant - a pink ramshorn hitchhiker. I'm sure there's eggs on the plants, too. It's getting too warm to safely order livestock here in AL, so this has all summer to get grown in and seasoned. I'll post updates on plant growth and whenever I add a new plant for now.
  5. Hey all! I've recently been facing an issue with dying invertebrates without any clear cause. My tank is a 10-gallon that has been pretty well-established and moderate to heavily planted. The water parameters have been consistently stable for months (tested weekly) at: pH: 6.8-7.0 KH: roughly 1.8 GH: 6.7 Nitrates: 20 I've lost 5x ghost shrimp, then 7x amano shrimp, followed by 3x nerites. The ghost shrimp died shortly after the introduction of some glowlamp tetra, however I watched them closely and never observed any foul play. The shrimp themselves never displayed any prey-like behavior and would never go into hiding either. In addition, the shrimp were a good size (roughly 1" or larger) so I wouldn't expect tetra to harass them. After I lost the ghost shrimp, I replaced them with the amano. Admittedly, they were very small (half-inch or less). While I never observed any foul play either, they DID go into hiding and I would randomly find a dead one out in the open. The puzzling thing to me are the nerites. I added 4 of them and 3 of them are now dead. The fish (combo of glowlamp and neons) have all been happy throughout their course in the tank without losses. Anyone know of any unaccounted factors that I may be missing? I know the glowlamps may be a potential culprit, but it's just odd, and I don't know that they would account for the dead nerites. I've never had this issue before and I'm rather bummed about the ghost shrimp as I had them for a good long while. I like diversity in the types of animal life in my tank, but at this point, I'm hesitant to add anything else. Thanks to everyone in advance! Martin
  6. Hey all! I’m currently towards the end of my small expansion to my small fish room for breeding. I’m getting into it for fun, and a way to support the hobby. I’m currently breeding red tuxedo koi guppies, red cherry shrimp, and sterbai Corys. What’s the most fun/ rewarding fish or invertebrate that you have ever bred? I’m curious about the responses.
  7. Disclaimer: All of this is due to my incompetence, so no, hydra didn't come to my house and rob me. So I had a little 10g tank that had some plants in it (the main one I'll be talking about is some parrots feather I got. Now, I cannot confirm nor deny this was actual parrots feather, because there are so many species that look like parrots feather and hornwort and...ugh its making my head hurt. But anyways, I had a little HOB and a sponge filter in front of the HOB, catching the flow on the way out. The parrots feather was catching the bubbles and the flow between both the filters. It was a kinda new tank (not really though, the bacteria wasn't at least), and it started growing some kind of algae on the very fine leaves of that plant. I hear a lot algae is not necessarily bad unless its killing the plants, and I thought the couple of cherry shrimp I was planning to keep would benefit off of it, and I would just leave it there. Big mistake. Fast forward 2 or 3 months and it was a a lot thicker and small and black, just coating the plants. But I was still in denial. I forgot to mention, the algae was some staghorn algae. But I didn't know at the time. With the tons of pond snails I had, they were creating a ton of molm and poop in the giant pea gravel I had (that I recently covered up because I couldn't plant any plants in it), and from that there were a bunch of small cyclops and copepods, and Im assuming from that, there were a bunch of hydra. About 2 months ago I finally gave in and looked into what it was. I read that it can be treated with Seachem Excel or increasing flow and it was from a lack of CO2. I also heard it can kill Val and Anarchis, both of what I had. I figured I'd do a plant dip, and took out all my regular baby tears, which was barely growing in sand, and parrots feather. It didn't really do much but turn white/gray on me and I decided to cut everything off, and now the Baby Tears just stands out more. From there I watched and learned about balancing your tank (probably the video from Girl Talks Fish was the most concise but anyways..). I just added some plants, covered the gravel and heavily gravel vaccumed (not that much actually, and a lot was in my HOB, which is a Tetra Whisper 40 literally filled to the brim with sponge. Literally. It died down a little and now theres only a wall or 2 covered in it, but I assume theres still a lot in the algae- some I still have in my java fern or whatever else plants. I wanted to add some fish live livebearers (I was already planning to add some platies) but then I figured that since it was a 10 gal, the platies would not let the shrimp at least make a baby or 2. So I figured I would put some shrimp first before the platies. But then I remembered the hydra and it was back to square one. Anything I should do? Also, anyone have experience battling Staghorn Algae and it turning really short and thick, but stringy enough to not look like BBA? Honestly I just want to cut off all of the affected plants, add some new plants and forget about it.
  8. I have a bad case of BBA in my heavily planted 75 gallon tank. I know I should have taken care of it earlier but I thought it would resolve itself. I believe it was due to my heavy use of coop iron. I recently bought a juvenile SAE but he does not seem interested in the worst case but just nibbling on the Amazon sword leaves that have smaller amounts of BBA. I’m scared of using Flourish Excel or hydrogen peroxide since I have invertebrates and baby shrimps. should I rip all my plants out that I worked so hard to grow or trim them all down to their base? I was going to not feed my fish for a few days and make them work for their living and help to clean up the tank in the mean time. i have very hard water and pH 8.4 which is typical of my tap water. Fluval 3 planted light (which I have turned off for now) . Stock - albino corydoras, khuli loaches, Royal fallowela, African dwarf frogs, mystery snails, bladder/ramshorn snails, cappuccinos, trumpets. Thank you for any advice!
  9. So.... I've recently had a fish with ich and the ich med I had was Tetra Ich Guard which has victoria green and acriflavine. How long after the dose can I put back my shrimps and snails?
  10. I "had" a thriving Spec V 5 gallon planted tank with just Cherry Shrimp in it and a snail that was doing great for about 9 months. Suddenly I started to see these little critters swimming around and they just kept multiplying and multiplying. They attached themselves to everything, including the snail and shrimp. Within about 2 months, the shrimp colony collapsed completely and only the snail survived. I nuked the tank by ripping it apart, scrubing and running it empty with bleach, throwing out the substrate, alum soaking a few plants to keep. The new tank has been running for about a month with only a snail and a single Amano Shrimp. Last night I saw a few Ostracods swimming around. I did read somewhere that their eggs are nearly indestructible and suspect that some survived the alum dip on the plant roots. So, I need a good suggestion for a tiny fish to control the Ostracods. At this point, the Amano is adult size and probably won't be threatened. EDIT: forgot to add that I was probably author of my own demise by over-feeding the Cherry Shrimp, but that isn't the case at all now.
  11. Hypothetical question. I imagine inverts' diseases and parasites would probably be very different from fish. Should you quarantine them before adding them to a fish tank? Obviously, if it's a shrimp tank, keeping new shrimp separate for awhile to observe any illness is a good idea, but if these are the first inverts you're adding to a fish tank? Is there any medication or treatment you'd give them as a precaution?
  12. Hi folks. I would like to have snails and shrimp in my freshwater tanks, but unfortunately in Maine (where I live) these are not technically legal to own (not one species of invert at all!). I’m hoping you can help. I’ve been in contact with the state department that oversees this, and the primary concern would be the invasiveness of species. In my preliminary dialogue where I posited a few species, they seem to think that Nerite snails and Amano shrimp seem to have a low chance of become invasive in the wild and worth putting forward for further review, so good news there. There is a formal process to have species considered, and the more information the better. My Google-fu is respectable, and I have lots of resources on how to keep these animals happy and healthy. What I need more of is information that would build a case as to how these tropical freshwater inverts would have a very low likelihood of establishing themselves in the Maine wild. Intuitively you would think as cold as it gets in Maine in the winter, that tropical animals wouldn’t stand a chance, but I need as much solid scientific information as I can gather to support this directly. My initial petition would probably be some of the most popular, common, and loved species: Mystery snails (Pomacea bridgesii), Nerite snails (Neritina sp.), Amano shrimp (Caridina multidentata), and Neocaridina shrimp (Neocaridina sp.). I’ve grouped the Nerites and Neocaridina together as they seem to be generally either very similar or treated as a group in the hobby as far as care and water parameters are concerned. I know that species such as Mystery snails can be invasive, but I’ve only found evidence for this specific species in tropical areas that quite closely resemble their natural habitat. If you have information otherwise though, please also share it as well. I respect the state’s efforts in this, and only want to put forth those species that seem reasonable. I’m having difficulty finding information that seems to be specific to this. If you have information or experience, or know of an expert in the biology or ecology, of these animals, and would like to help us aquarists in the frozen tundra have these awesome animals in our tanks, we would appreciate it. Thanks in advance for any resources you may have or suggestions. I know this is a bit out of scope for the forum.
  13. I have a 5.5 gallon shrimp tank with freshwater limpets that I HATE. They constantly cover the glass and look awful. I had been told that they boom and bust and that if I ride it out they won’t be as bad. Well it’s been a year and they’ve been crazy forever. Doesn’t matter if I starve the tank or feed a ton the population stays at the same insane level. I’ve tried manual removal, I’ve tried feeding the shrimp in a dish and removing after an hour to make sure there’s no leftover food for them. Nothing works. I’m at the point where I might try to remove all of the shrimp and heat the tank super high to kill them? Anyone had limpets and gotten rid of them successfully?
  14. Help with hydra? I have a 35 gallon tank with 2 angelfish , live plants and a Chinese algae eater. Noticed a few hydra today. Any recommendations on fish added to my aquarium that may eat the hydra or is chemicals the only route? Since I am not breeding them is it really a big concern? Newbie here 😐
  15. My brittle star is curling up and secreting a film..... do i need to pull him from the tank or is that what happens in a new tank its my first brittle star 😫
  16. Is aquarium salt safe for crustaceans? I am dosing a 10 gallon with 2 tbs of salt and I want to make sure it’s safe for the dwarf Mexican crayfish I have in there.
  17. What is considered to be a good ppm of calcium for shrimp, crayfish, and snails?

    I was looking at articles about the quarantine trio, and intend to purchase for new fish. I also deal with large quantities of shrimp. Are these quarantine meds recommended for them as well? Many shrimp are imported and it makes me uneasy adding them to established colonies.
  19. Hello all, I am getting a betta for my shrimp tank but i don't want to quarintine him because my qt tank is a 10gallon, and his permanant tank is 5 gallons. And I don't really like the idea of downsizing him, especially if its a betta that probably hasn't been with other fish, meaning it probably won't have any parasites or deseases. Will invertibrates spead deseases to fish or vis versa?
  20. I have always assumed mulm was some sort of combination of living and dead bacteria. I was always happy to see it because I assumed the mulm is processing fish waste from something more toxic to something less toxic. But that is a least 2 assumptions so far. I haven't googled this yet so I am throwing the question out to the forum. What is mulm?
  21. Anyone else have Mexicain dwarf crayfish? They are so full of personality. Here is the dad (Henri II) with his daughter (born August first). And a picture of her when she was few days old. 🥰
  22. I am not sure if hydra qualifies as general discussion or a disease? I found a small population of water hydra in my guppy fry tank. For a while I was taking them out on the rock they were attached to and seeing if the pea puffer was interested (no). From observing, I never saw a fry get caught or close to caught by one. The fry eat floating detritus worms and they sniff at any floating hydra but then go ew and swim away. I know they’re a sign of over feeding, but I’m worried about balancing that against accidentally starving fry. Are they something to be legit worried about or do I just run some mollies through the tank once the fry are out or what?
