What about having some zebra danios? They are constantly moving around, and if you have a nice school of them going, I think that would look rather nice. Most big chain stores sell them, they're quite hardy, and you can get different types of zebra danios. For example, you can pick out some long-fin ones or perhaps the ones that are spotted instead of striped. And, usually, they don't cost any extra if they just sell them as the group "zebra danios." The difficulty would come in trying to get the employee to catch exactly the one(s) you want 😄 I will caution you though to use a lid. They are known to be jumpers, and they have leapt straight out of my past tanks before I ensured that they had nicely-fitting lids. I was also told that if you have floating plants, they are far less likely to jump. Also, the floating plants will help you with the water change plan you mentioned you are trying to work out.

In case anyone has been considering Rosy Barbs, I just wanted to share some of my anecdotal experience in keeping them so that maybe others will have a few things to consider before trying them out. Looks First off, they are really pretty fish, especially the long-fin (hyphenated?) variety. The males color up and exhibit some amazing colors, and even the females are a wonderful, bright yellow. The single male I kept in my goldfish tank for a couple years was a wonderful bright orange red. He became even more striking when I started feeding the tank krill flakes. Behavior They will DEFINITELY pick on, nibble at, and help keep black beard algae in check. In my case, it was utter extermination with the single male I had in my tank. I later added a group of females and another male, and they utterly stripped that tank clean of any and all traces of BBA and string algae (which I suspect came from my Marimo moss ball). They are supposed to be relatively peaceful fish, but I think that is very much on a fish-by-fish basis. The single male I had for a LONG time with my goldfish never once picked at or nipped her long, flowy fins. The new group of females and male were a rabid bunch of fin nippers. As such, I had to re-home them and kept my super docile male, who at this time was about 3.5" from nose to peduncle (longer if you count the long, flowy fins he had). This male, unfortunately, died when I was moving. I'm not sure how or why. I had a battery-operated air pump and air stone in a good-sized cooler with clean water. I think it may have been the stress; he stayed with us a little while after the tank got set up (same day as the move), but he never seemed to recover. I really liked that fish. I didn't get a replacement rosy barb for a while, and BBA came creeping back and invaded in force. I caved and bought a new male, long-fin rosy barb. When he was introduced to the tank, that BBA went from looking fluffy to looking mowed down seemingly overnight. The new tank savior also suddenly tore into the goldfish after living peacefully together for more almost a month. It was just as fast and brutal as the BBA, only instead of "seemingly overnight" it all happened in one "literal night." Conclusion These are excellent fish, and they look absolutely phenomenal. They didn't seem to give any of the fast-swimming fish any trouble, nor did they give the dojo loach any trouble, and he just sat at the bottom hiding under plants a lot of the time. But it just seems like a real coin toss whether you will get one with a violent tank boss personality or one that is a zen master and hair algae mowing machine. Be careful and watch them closely if you have any fish you may have concerns about. I wish you the best of luck in keeping them if you choose to have them in a community tank. Final note: The goldfish tank I kept mine in was a cold water tank and had no heater. My wife keeps the house about the same temperature year-round, so it was just "room heating/cooling."

These ramshorn snails started to appear in my tank after my goldfish and dojo loach died. I haven't sat and watched them do it, but I am also fairly certain that they eat black beard algae (BBA). I have found them, on more than one ocassion, in the center of a green circle on an anubius leaf that was formerly covered in BBA. I find them to be cute and helpful.

By "microorganism" do you mean you can only see them with microscope, or can you see them with just your eye? If you can take a picture of them, it would be nice to see what they look like. They could have piggybacked on your plants, spider wood, or gravel. I honestly wouldn't worry too much about them though. Microbes are everywhere.

I asked the same question some time ago. Here are some non-fishfood fish food for goldfish: -garlic (chopped fine) -broccoli (steamed as I would eat) -grape (chopped fine) -red lettuce (no need to blanche) -frozen peas (no shell) I also feed mine some dried grammarus stuff for turtles.

On this episode of Pimp My Fish, we give barbels to this Fantail Goldfish and give this Rosy Barb the insatiable hunger for Algae of an Otocinclus!!!

Fancy Goldfish (as above) Folks will see a puffer and go, "Dang, that's an exotic fish. This person must really be down with this fish keeping thing."' HOWEVER, when folks see a huge, fancy goldfish, especially something like a plain old fantail, but it's GIANT-sized, people will go, "Whoa . . . I tried keeping one of those once, this is what it's like when it's done right."

Chinese Algae Eaters . . . not Siamese Algae Eaters (we cool with each other) They always end up going aggro and nomming on other fish's slime coats even with ample food. Also, aesthetically, not my thing at all. WAY better options for algae control.

If they are colored like The Ultimate Warrior's Ultimate Face Paint, they are most likely colored like wild guppies. In short, they are the color of "Live strong! Act Bold! Be Brave!"

So some people "oops" some fish, and others "oops" aquariums. Those are some good "oopses" you all have there.

Ah, I missed the the "in general" bit. I guess I can see how saying the total length of the fish can be helpful in gauging whether it will have issues turning around.

Thanks for all the input! What about when people speak in general, for example one hobbyist to another about things like how big a certain fish gets?

I have a question about fish measurements. When you hear that a fish grows to a certain length, what measurement are they probably using? I hear a lot of descriptions for how big a fish will get, but what do they mean when they give those numbers? Is it the green line, from the nose to the base of the tale fin? Or is it the purple line, from the nose to the tip of the tale fin?

I was taking the kiddo around COEX Aquarium here in Seoul, and I came across these cute babies in the axolotl display area. Note how they don't have their back legs yet and are see-through 😄

The detritus worms probably started getting bolder and more numerous because they don't have those tetras picking them off any longer. The fish in your other tank probably snap them up, unless they are so big that the worms are not worth the effort.

Hi there! Congratulations on getting yourself some pea puffers! I love those fishies! I miss my old ones from college. Cory has said a number of time that the med trio that Aquarium Co Op sells is invertebrate-safe and plant-safe. If you wanted to, I don't think that a "quarantine in the main tank" is a problem. In other Aquarium Co Op videos, "treating the whole tank" was an option if every, or most, fish inside got sick. It might also lead to less strain on the fish because you don't need to net them out again when you move them from the quarantine tank to their new happy home. As for feeding them . . . I don't know. I've always fed while the fishies were quarantined. *looks out into the forum* Can I get a second opinion? A note on pea puffers: You have a big enough tank with lots of stuff to break the line of sight and divide up the space, right? They're cute as hell but can have the ferocity of a full-grown wolverine condensed into a tiny package when it comes to turf wars.

Thanks for the specifics! I needed to look up that filter on Google, but from what I see, it could definitely have been the reason your water is that color. I took a look at the substrate you are using, and yes, with using special substrates for plants, they will cloud the water just like your picture shows. As you deduced, the filter's suction cups probably got "unstuck," it fell over or near the substrate, and then it probably started to churn the substrate with the water jet(s). If you were home, you would have seen it on its side or pointing down and fixed it immediately, but since you were away . . . brown water. I had thought that churned substrate (as someone had already mentioned) might be the case, because when I first started using special plant substrate, I made the newbie mistake of putting the substrate in the empty tank and then just dropping the water from the top of the tank. My water looked a lot like your picture, and after a day or so, it settled down. Enjoy your clear water! (...when it fully clears up) PS: We'd love to see your tank when it's not cloudy Post a picture!

I had a blackbeard algae (BBA) problem a little while ago, but I effectively starved the rosy barb in my tank by feeding just the goldfish food, and all that BBA got nommed quick, fast, and in a hurry. Rosy barbs are cool-looking fish and are highly underrated in my opinion. I was told they can be aggressive, but mine only did light chasing, and now that the goldfish is HUGE compared to it, it just makes way for Loppy Wigglebutt. Plecos have a tendency to nom softleaf plants. Otocinclus are cleaning POWERHOUSES, but you mentioned angelfish, and I am not sure whether the little Otos will get shredded. Others will know better; I have never kept angels. You should get a small group of Otos though if you keep them.

Could you give us some specs, please? More information can help give people a better idea of what might be going on. To start . . . I see an air pump on the left side. What kind of filtration do you have? What animals are you stocking in it? Any thing that burrows? What substrate are you using? Did you recently add any pieces of wood to the tank? I'm guessing you did water changes already, so what are your new test results?

I had planaria in a tank I designated for cherry shrimp, and it freaked me out at first when I started reading about how bad planaria were for shrimp. The scientist in me went, "Let's see how it goes anyway!" Then, after 2 months, there were lots of shrimplets and a few fewer planaria. I then introduced a couple guppy fry into the tank, and the planaria (and visible detritus worms) disappeared faster than food in front of a goldfish.

As for the tank size, you could measure the tank dimensions in centimeters. Once you find out the cubic centimeters, that is equivalent to mL, which you can then convert to gallons. width in cm X length in cm X height in cm = total cubic cm = total mL 1000 mL = 1 liter = 0.264 gal Or you can just take the mL to a site that converts it for you. @Cory's video on goldfish suggests 20gal/goldfish plus at LEAST 10 gal/additional goldfish. For 4 goldfish, it comes to 50 gal. However, if the are common goldfish, those are going to be big fishies if fed well.

Just to pass on what is said pretty often in Aquarium Co Op videos: "If it fits in the other fish's mouth, there's a chance it can get eaten." I don't know about koi. but Goldfish will totally om-nom-nomnomnom (eat) any fish they can catch and fit in their mouths.

Sometimes, blurry ain't so bad 😄 "Mud Guppies" can be pretty colorful

After replying to another post, I wanted to share one way I get clear(er) pictures of moving fishies with my camera phone. It's simple really. 1) take a video of the fish 2) scroll through video for a clear frame 3) screenshot it and crop My rosy barb picture, captured using the method above...he's a long-fin, right? At least I think he is, the fins seem longer than other rosy barbs I've seen.

Looking at the pictures, I can't tell 100%. I have seen females with long dorsal fins before. The anal fin isn't exactly captured there. I think a picture with a side view would be better. Since fish are always moving, you could set your phone camera to video, record a clip, and then screenshot a clear frame as you scroll through the video manually.
