I have 3 of these cardinal tetras and they are lovely fish and get on with everyone in my tank such as neon tetras, glow light tetras, lemon tetras, cherry barbs and zebra danios. I am planning on getting some more in my community tank because they show lovely colours and they bond with other fish and swim with them especially neon tetras. I would advise you to get these lovely fish in your tank.

I have twelve of these guys with my Neon Tetra's and my green Neon Tetra's which is sometimes called the False Neon Tetra. They are all Cousins and all school together and they also group off and they mix up, so I'm unsure if they see each other as all the same. The Cardinal Tetra is Beautiful, but so are their cousins, and if anything the Green Neons are colouring up just like my Cardinals. They love to School in the Flow and its a Beautiful Sight. The Green Neon Tetra's usually start this and then the Cardinals join in and the Neon Tetra's. They all seem so happy together and make my tank look Beautiful. I just can't stop watching them!

I bought 6 of these fish for my 30 gallon tank over a year ago now. By no means an 'expert' fish keeper at the time i didn't expect to have much luck with them (Especially as they were very very small at the time of purchase). The store owner recommended many 'Cardinal water products' that i declined and i took these fish home and hoped for the best. A year later i have 5 healthy and quite large Cardinal tetra's (i lost 1 within a few days of purchse).
These fish really are beautiful and peaceful. They live happily with my Lemon and Flame tetra and a recently purchased pair of dwarf gourami. The flame tetra often show courting and mating behaviour which seemed to 'excite' the cardinals into courtship and mating behavour themselves. Although i don't intend to breed them - for those who do they seemed most willing to mate whilst they were younger.
All in all i havn't found them anymore difficult to keep than any other fish and have avoided the use of expensive 'Cardinal specific products'.

I have a shoal of only 5 guys in my 110 liter tank with 3 amazon algae eaters. I am restocking my fish tank soon but until then these guys are being the most perfect fish you can get! I love this site by the way.

Cardinal Tetra... As suggested, it is one of the most popular fishes in the world. I bought about 80 fishes for my 3 and 1/2 feet tank. All the fishes were great and displayed shows of blue and red colorizations. Needless to say, it is my favorite charachin of all time next to the neon of course.
Still, i would recommend all aquarists to buy this fish, but it will be at its best when the substrate is dark and soft and acidic waters. It does better in a heavily planted, well-balanced aquarium.
By the way, Great Site!!!

I have 4 of these fish in my 20 gallon tank with 2 congo tetras, 2 albino congo tetras, 2 corydorus catfishes, 2 glowlight tetras, 2 orange von rio tetras, 1 von rio tetra, zig zag eel, and a dwarf african clawed frog. These are very cool fish and when you have a group they school very good. These fish are compatible with all fish of the same size range. Cardinal tetras are very popular fish and are from the amazon, one of the rivers in the amazon which is the the Rio Negro has many cardinal tetras and when Cardinal tetras are wild caught they usually come from this region. overall...these are nice fish.

I have 5 of these guys right now. I was thinking of adding some Neons and was wondering if they will all skoal togther. If they don't, I will probably just add more Cardinals instead.

    These fish will not know the difference between them and they will school together. I just bought three and they started to school with my lonely neon tetra.

    Yes. When I had 4 neons and 4 glolites, they school together.
