It's a little thing, but I finally confirmed what I knew: my 'juvie' goldfish are breeding adults 😔 The lionchu has breeding stars, which means the oranda is the female. The one eyed oranda I impulse purchased at a LFS also has breeding stars, but he gives me old man vibes and doesn't try to chase the female oranda (which the lionchu does often). Obviously since I gave one of their babies away two weeks ago I knew they were breeding, but it's nice to confirm, I guess. I'm not enjoying being sick but it's given me lots of time to observe my fish 🙂

Congrats! Are you planning to keep them in a breeder box or let them roam the tank freely?

Another day, another co-op order...first one of the year!
You know you're a nerm when you've been looking forward to getting scraper blades for weeks...

Visited a couple LPS's today, then finally got around to rehoming the goldfish fry. Finally my ricefish eggs can hatch in peace 😅

New light: acquired!
Excuse the mess; haven't done maintenance on the tank in a few weeks.

Replying to my own topic as the culprit and solution has been found--
The fish was wedging itself into the rockwork, presumably to get those morsels of food that fell in between the cracks. I found him stuck one day and rearranged the rocks, and he's healed pretty well in the intervening two weeks.

Lol thank you, one of my favorite Sith Lords! So in your case you ended up over-filtering and had trouble keeping nutrients in the water for the plants? That was one of my main concerns.
Back then my problem was not using a strong enough light (I have an unconscious affinity for tall tanks, I guess) nor was I dosing enough ferts, so the plants were just kind of stagnating, lol. This time, I wanted to take it slowly and not go wild with filtration since it's expensive, so I just keep testing water. I'd rather buy an extra sponge filter as needed, than start with a giant HOB that blows my poor fish and salvinia around.
In my current setup that's eating nitrates like crazy, I've got a strong light, planted tank substrate, and liquid ferts. The sponge filter is too large, but the flow is so minimal that it's kind of turned into an oversized eyesore that I'll be glad to move into a larger tank soon. At the moment the stocking is low, with 6x adult ricefish, a goldfish, shrimp, and snails, but I'm overfeeding because the ricefish are breeding, I want the shrimp and snails to breed, and the goldfish is a growing boy.
My opinions and rambling about my tanks aside, if you haven't listened to it yet, I recommend this video by Cory, as well as one I can't remember off the top of my head, but I think it's about changing water too much.

re: filtration, when I first got into the hobby I overfiltered so much (like, an Aquaclear 50 + kit HOB for a barely stocked 29g), but after coming back to fishkeeping...I probably underfilter. The exception is the goldfish tank, which has two HOBs, but one is primarily for filter floss/seeding sponges for new tanks. I'd like to get that on just one sponge filter one day to keep the energy cost down, but I'm going to use what I have for now. All of my tanks are planted, and I've been struggling to keep nitrates above 20, so I have to dose ferts about twice a week in the most heavily planted one.
(also, I love your username.)

Yep, it could definitely take up a lot of tanks depending on how you go about it. Fortunately you can get away with some relatively small containers for some shrimp as temporary containers.
And if you have any extra sponges you could possibly stick those in the cover of an established tank. Then when you need to setup an additional container for shrimp you could move that sponge and some of the tank water over and more or less have a cycled setup. Haven’t tried it, but possibly shove an air stone in a pre filter for a quick diy sponge filter. Obviously wouldn’t work as good as an actual one. But maybe good enough to be a temporary option.Ooooh I'd never thought of the air stone + prefilter. I definitely want to try that, since I have two mulm-filled sponges in the tank for the shrimp.

Thanks! Now that they've settled in some are definitely showing dots and darker colors, so I'm excited to see what the shrimplets will look like.

I haven't yet had luck with treating swim bladder in bettas so I can't offer any advice, but I'm glad your fish is doing better--following this topic for advice others offer.

I try to tell my ricefish they need to lay their eggs on the spawning mop, not just on the plants...I also scold the goldfish when I put my hands in the tank and they go and nibble on my arm.

Tank Size: 36g bowfront, with two additional goldfish not showing any symptoms
pH: 6.8 (the regular pH, per the LFS and my own tests, is 7.5)
Ammonia: 0
Nitrite: 0
Nitrate: 10
Hardness: 100
Alkalinity: 0-40 (usually around 40-100)
Temperature: 78
Right before bed I noticed my Oranda's scales are falling off. Panicked, dosed maracyn, 1tsp salt per 10 gallons, and added crushed coral. I'm not sure why the pH is so low; I've checked another tank and it's also 6.8, so I'm not sure if the water company is adding something to the water. I might wander to the LFS tomorrow and ask if they've noticed anything.
I haven't changed anything in the tank in the last week; on the 19th, I added some Fluval stratum and plants, as well as moved things around. Yesterday, I fed them rinsed, cooked carrots, Hikari Vibra-Bites and also brushed off some sand from this fish. I also topped off some of the water. Today I threw in some sinking pellets they've never eaten before. Other than those new foods, they've been eating the same food (Repashy, Xtreme) as they have been since I got them in September. I did not notice the missing scales when I was looking at the tank earlier today, nor when I fed them.
Is there anything else I can do for the fish? Or just wait and see?
(apologies for the lighting; the only light on that tank now is a purple grow light)

I've been thinking about this a lot--one of my female ricefish has a hump back. It doesn't affect her QOL in any way: she is the biggest of the bunch, gets the most food, and honestly is a bit of a bully. I could (and maybe should) move her to the goldfish tank since she's not aesthetically 'perfect'; she's too big to be eaten by them, so it'd be just to prevent her from spawning, but I also don't want her to be lonely, lol. I haven't figured out the answer yet, though.

It’s a numbers game for sure. And from my understanding about breeding shrimp, though I’ve never bred from wild, you want to encourage the desired trait as much as possible. So while those 18 shrimp are breeding look through from any shrimp that there’s any coloring on. Move them to a tank by themselves, no other shrimp, and breed those together. Continuing to add others with those colors and removing all without, less or different color.
Allowing a colored shrimp to breed with a different colored, or wild, can cause that color trait to revert back to the wild shrimp appearance or mutations to another color. While you may want to do that with some of them to see what you get. If your specifically wanting red than I would suggest trying to only breed that trait with others of that trait whenever possible.
And if you find a buried female with the trait you desire, it might be best to isolate her until they hatch. Then add her with the other of that trait. probably easier having the babies in a small isolated container to see what traits come up than trying to get them out of another tank.
Definitely an interesting project no matter how you go about it.
Mark’s shrimp tanks has some good info, has website and youtube. But think most is with regards to breeding an already established strains versus breeding for a strain.Thank you! After watching the shrimp settle in over the day, the berried females are definitely darker, though I suspect that might also be because they're older than the others--they are about 2-3x larger than the smaller ones. I don't have the rack and extra tank to hold the selected shrimp, but maybe they'll hold onto the eggs for a week or so. I'll definitely check out the channel you mentioned!
From the charts I've looked at this afternoon, it seems like the initial variants I'll get are either red/brown/yellow or red/blue/brown depending on the phenotype of the wild type. I'd wanted to aim for red cherry since it seems like the easiest to get, but I'm certainly not opposed to a different color 🙂

Sounds like a fun project!
I think the trick with small organisms with a short generation is to use massive expansion followed by repeated bottlenecks. In other words, make your 18 shrimp into 180+ (until you run out of space, food, or patience), find the most colorful or interesting 18, cull the rest, and start over.
I work with genetics in my lab job. What you are looking for is a spontanelusly arising mutation or recessive gene. The fastest way forward is a pure numbers game. Once you get something cool (any unusual color in this case) you THEN select toward that thing. Say you get one pinkish shrimp in your first 180. You keep it and your 17 healthiest shrimp. Then by the next 180 you should have several pinkish shrimp, and so you repeat. Once you have 18 healthy pinkish shrimp, you then choose for the darkest pink, etc.
Your wild type shrimp theoretically contain the potential to deliver any of the colors known in neocaridina. It is just a matter of breeding an insane number, and watching closely for the odd balls.
Thank you so much! This is exactly the advice I was looking for; I wasn't sure whether the red would be a spontaneous mutation or something recessive, so I'll keep an eye out for both 😄
Ultimately I suspect I'll run out of interest before anything else; there are plenty of tanks/ponds around for my culls to go into, lmao. But biology and genetics has always interested me, so I hope the fascination will stick.

After stopping by a few local pet stores today, I found some wild-type feeder Neocardinias for sale at a reasonable price, and decided to get my red cherry shrimp breeding project started! Ideally, this thread will be proof that these shrimp were not imported and were not bred here, where it is illegal to import aquarium shrimp, if I try to sell/trade these to a LFS. Regardless of the outcome of the breeding project, they can just be pets and chill in the tanks. Either way, I think it's a fun (and low cost!) breeding project, especially compared to my ricefish 😭
A bit of background: where I live, neocardinia davidi are an invasive species, released by aquarists into local waters and are out-competing the native shrimp. Accordingly, neocardinia davidi are sold as feeders. (further reading here and here)
I picked up a bag of shrimp from two local stores; if you're a local to Oahu you'll know which ones I'm talking about. For brevity's sake, store one is KPS and store 2 is ELP.
KPS: 2x 10 shrimp @ ~$2.50 per 10.
ELP: 2x 8 shrimp @ $1.00 per 8 Noticed at least 2 shrimp were berried.
The current cost of this project is about $8, which includes some Hikari shrimp food I bought at ELP.
As the KPS shrimp came from...kind of a nasty store, they went into the orange ricefish tank, as there's more detritus, algae, etc. for them to snack on. ELP shrimp went into the Daisy's ricefish/bronze cory tank.
I'm going to be setting up a breeding for profit rack soon, with a 30g tank and some 10g growout tanks. A group of the shrimp will live in the 30, and some will be going into the growout tanks to take care of any fungus-y eggs.
I understand the basic principles of breeding and culling, but I'm interested in literature about breeding RCS from wild type neocardinia, as well as any tips you folks can offer! Should I be looking to selectively breed the darker/patterned ones? Or can the red develop another way?

Goldfish fry! Almost two months old (discovered him on November 5).

I couldn't accurately sex my ricefish until they started spawning, but now I've gotten pretty-ish good at it.
The females tend to be a little larger and fatter, with shorter anal fins like you and kammaroon said. The male's anal fins remind me of a skirt.
I attached a picture of my ricefish, I foolishly put fast-moving orange ricefish with transluscent fins on orange substrate, so...it's also outlined for you. You can also see the size difference. Hope it helps!

I haven't gotten started yet, but one day I would like to attempt to get the red cherry shrimp out of the wild types, as the red ones are illegal to import, but wild types are sold as feeders (some people have them, but you can't buy/sell). After my goldfish bred earlier this year I was seriously considering breeding for a longer bodied version of fancies, so they'll have an easier time swimming, but I don't think there's a big market for that 😞 maybe as a side project in 2021.

I have absolutely no idea other than what I just googled because your question made me curious. But according to the forums I browsed, they can interbreed and panda cories tend to do it the most often? However, I haven't been able to find any scientific studies on it, only anecdotal accounts and people just saying 'don't do it'.
