I have two albino corys, one Julli cory and two emerald corys. They are in a 55 gallon with one pangasius cat, a pearl flowerhorn, a pleco, a banjo cat, and a spotted green puffer. Everyone gets along very well. The corys love to school together and you can tell the albinos are a pair - they are always together. I keep my temp for all of these fish at 78 degrees and feed a very large variety of food. The corys love bloodworms and beefheart! They have grown a lot since I first got them and I add 1 tablespoon of salt per every 5 gallons of water in my tank with no problems to these fish. Everyone in this tank is extremelly healthy and I have not had problems with any of them. Good luck to everyone!

I used to keep just one cory with 3 angelfish. i thought it was a dull fish, always still and at a corner, never active except when frightened. however, after adding 5 cories -- it totally changed! it got lively, chased after them curiously, and appeared sniffing at them! He loved their company! Now they are often travelling together, and they share food like good siblings. The best thing about them -- they never get jealous over whose share of food is more! Avoid salt at all, they are extremely sensitive to it.

Very peaceful, and good cleaners of your tank! Feed them every other day, so that way they will eat the algea, and the left over food on the bottom from the other fish, dont worry they will never starve! They are good cleaners and dont get very big (only 2 inches). When you want to feed them or give them a treat, buy them food tablets that sink down, and watch the fun unfold! Very active throughout the day.

Emerald green Corys are very easy to care for and very intelligent. They do well in tanks above 5 gallons, but you need to be careful about how tall the tank is. Corys can actually breathe air if their gills are wet, so they occasionally swim to the top. Because they spend so much time at the bottom that they can't really swim too far straight up, so the tank can't be taller than a little more than a foot and a half. I would recommend them for anyone who has a freshwater tank, though you should definitely get more than one. They get sicker when they are alone; take it from me.

I've got 2 cool stories about corys. 1: I once had a cory jump out of the tank during a water change. That little fish used its fins to propel itself halfway across the room, no problem with being in the air at all!

2: I once had a male beta and 2 corys in a tank together. Male betas are really aggressive and usually attack other fish by putting up their frills (like a lion mane). My catfish had absolutely NO problem with this and just swam right by. I think that made the beta confused.

Last thing: I once had two corys get sick, though their other tank-mate had no problem. They kept falling over on their sides and being unable to get up. When they swam, they were fine, but when they stopped, they just fell over. They could hardly breathe because their gills were pressed on the floor. They died in 3 days; no medicines helped. It was creepy. If anybody knows why, I'd like to know so I can fix it if it happens again.

    It's called swim bladder disease. Try this stuff called Fungus Clear. It says it'll help, and it worked OK for me.

The fish in the pics are not emerald corys, they are bronze corys. The difference is in the dorsal fin. Emerald corys have some 13 dorsal rays - the fin extends back to the adipose fin. Bronze corys have like 7 rays, and there is a clear gap between the dorsal and adipose fin....like in the pics.

Someone help!!! I have the strangest external parasite problem in my tank. I have Gouramis, one Cory and one Albino cat. The Cory, and ONLY the Cory is affected. It gets these little white dots (no, it's not ich, I've kept fish for 30 years and know what ich looks like), they stick out from the body and get longer like white spikes or threads - not very long, but definitely growing away from the body. I read books, browsed web sites, went to pet stores and asked many experienced people and no one knows. The parasites don't bother the other fish at all. I scooped the Cory out and quarantined it for three weeks. The moment I put it into the quarantine tank, the white organisms were gone - must have fallen off in my main tank? Isolated Cory for three weeks, no sign of parasites and none in my main tank, so put Cory back. A week or so later, white thread parasite worms are back on Cory again. They aren't visible swimming around in the water or on other fish. This time I treated the main tank with chelated copper, general remedy for external parasites. Very shortly after I put it in the water the Cory reacted and the white parasites came off it's body on a clear membrane that separated off Cory's body. Copper treatment is supposed to be good for one month. Parasites recurred a few weeks later. So I just treated again (Sept 28). This has been going on since early July!!! I wish I could identify what I'm dealing with so I can get RID of it once and for all. Has anyone had this experience? I lost one golden gourami, but with no sign of the parasite. The others are okay so far, but get stressed as treated water kills the good bacteria in the mulm layer and water quality is affected by treatment. Albino cat is fine, as if nothing is going on.

    I had that happen to mine and it's from hard water. We switched to buying water from our grocery store and it went away.

    Pretty good! nice Pretty good! nice to see that all the fish are much active now and very fast lol. I saw soeonme suggesting you to get bala sharks..this is a BAD idea because they get over a foot long and will see smaller fish as food. I would suggest Black Skirt Tetras (they are schooling fish and i had them before and they are amazing, mine get very dark at night and they are cool fish) or you can go with some Gouramis. Dalmatian Mollies also pretty cool fish.

I have 3 green corys in a ten gallon tank with three platies. They all get along well, except one of my corys sits apart from the other two. He/she seems perpetually sick, breathing fast with whitish blobs at the base of his/her topmost fin. That fish used to have fin rot , but I cured it and it seemed fine until recently when it started showing the symptoms I mentioned. I want to help it, but I don't know how.

    I had a similar thing happen. Try this medicine made by Jungle. Its called Fungus Clear. I discovered that it worked while medicating another fish in the same tank. I couldn't believe that it cured my catfish so fast. It could have been something else, though.

    You should be fine with this fella in a 30 gallon. They grow to about 4 inches. Is this the only fish you have in the tank though? Make sure you check tank conditions.

I have Emerald Cory fry! I had a pair of adults, the only fish in my tank, and yesterday I saw the tiny fry darting around the bottom of the tank! I am so excited! I have kept fish for about 6 years, and this is the first time that any have reproduced.
