Everyone says Congo tetra's are timid.I have 5 and they dart around scaring all the other fish. They are also aggressive eaters and hog everything. They have eaten many of my smaller schooling fish. So none school anymore. I have a 75 gallon with now only 5 cardinals,5 embers, 3 cherry barbs,3 celebes rainbows,6 neons, 5 glow fish, 2 cory panda's.

NEVER feed Congos flake foods.. I feed mine a mixture of 4-5 different blends of frozen fish food found in the freezer section at your fps. Take one frozen blister capsule from each package and allow them to semi un-thaw in a small plastic container... Mix them thoroughly and refreeze. Your Congos will love you for it and their colors will pop like you have never seen them before however, it is up to you as to how often you wish to feed this mixture to them per day. Just remember, the frozen stuff is usually very high in proteins and fats so it should be noted that just a small amount be fed. I keep two (2) males and two (2) females in my 55 gal. By keeping two of each it allows the males to compete as the alpha male thus pushing their pigmentation of orange and blues as well as silvers out naturally.

I have had 5 males and 2 females in my 325 litres tank for about 4-5 years, one of the males has been around for over 5 years... I just this morning noticed that all the males have a reddish tinge on their dorsal fins, all of them in the same place. I have never seen it before and am wondering if anyone else has? I am wondering if it isn't some sort of mating display? Any help or knowledge on this would be much appreciated. They have always been and looked magnificent fish, definitely a nice addition to any tank that you want some larger schooling fish in. Very lively and active. Would definitely advise everyone to try them out.

I've got 19 of these beauties in a 100gal in an african biotope tank with other congo basin species of fish, mixed sex group, the males look stunning. All the males are around 4 inches and what I thought was fully grown. Looked in the local fish shop today and they had large congos for sale. a good 5 inches + they dwarfed my fish. The person who said they grow this big was talking complete sense, nothing documented online for congo tetras of this size but they do exsist and presumably all have the potential to grow to this size (unless they were hormone treated or something). Fantastic fish, definately more rowdy than this article makes them out to be, voracious feeders they swarm and tear food apart like a group of beautiful pirahnas, all my fish are large semi aggro and the congos hold thier own wonderfully! Just another thing, I wouldnt keep a group of these in anything less than a 4 ft tank, they certainly like their swimming space!

Can albino congo tetras live with discus?

    I wouldnt put the two of them in the same tank because of the different temperatures they do best in.

These Fish are amazing, the colouration of them is usually not seen while at the store, but once they grow up a bit they glow (more obvious when not looked at straight on).

They can reach a max length of 5" tho, so make sure you have a larger tank for these fish. I have 4 in a 75Gal and they play well, tho they are agressive when fed (will knock other fish out of the way for food)

    They are certainly a beautiful, and exciting specimen for most community aquariums!

Beautiful fish. I have 7 in a 30 gallon in addition to some other fish.

Someone here said they reach a max of 5 inches, but everything everywhere I've read said that males get to 3.5 inches, and females stay closer to 2.5 inches.

they seem to get along well in a community tank.

Plus, you have the joy of having very rare tetras which 90% of other people don't have.

I take pride in having rare fish. And the Congo's fit right in with my African Butterfly, Leopard Ctenopoma, Female Krib, and cories.

    I have some of these & am going to expand the school as a larger fish in the tank died. They are beautiful & mine are not timid at all. I have the ones that look more olive green/electric blue & I am having a hard time finding more of those. Mine are getting along nicely with African Red Eyed Tetras (another less known, awesome fish! - not to be confused with Red Eye Tetras) a Giant Danio that has a blue-green sheen to him, a large killifish (that I believe was mislabeled as a gardneri) & a couple of peppered cory cats. I have a blue-green iridescent thing going on somehow... I have a Leopard Ctenopoma that i would be afraid to put with these because he is (& so has every other one I've owned) a little on the aggressive side. They like to chase other fish, especially when the lights are out. They are one of my favorite fish.

Hi my name is Ethan from LI in NY. I have a pair of congo tetras and a pair of albino congo tetras. They are nice color full fish. I have mine in a 20 gal. tank with a clown pleco, corydoras catfish, 3 glowlight tetras, 3 cardinal tetras, 2 von rio tetras, 4 orange von rio tetras, zig zag eel, and dwarf african clawed frog. These fish can get up two 3 inches long but albino ones only 2 inches long. Not only are albino congo tetras smaller but they are also much rarer. In fact I have only seen them in a petstore twice. I would definitely recommend these fish.

I have 3 albino versions of these colourful tetras. Mine are currently 2"-3". These fishes are rather scrappy fellows. They love frozen bloodworms and often fight for it. These fellows grow quickly!I first bought them in july when they were 1/2"-1".
