I just have a few questions about the rainbow sharks, and I hope I am posting this in the right area.
How big do they get?
I am getting a 45 gallon tank; is this large enough for one of them and other fish?
What fish are compatible with them?
How often are they fed?
these will only get about 4-5 inches in length. yes a 45g will hold more than just the rainbow, they should be fed twice a day( in the morning and at nite) and they are compatible with fish like barbs and tetras
Rainbow sharks are very territorial and it would probably be best to only have one in your tank....They also can get up to 6 inches long....I wouldnt reccomend tetras (At least the smaller varieties) with them.....Your probably better off with a small shoal of barbs of some kind......Rosy, Odessa or Denison (very expensive, but awesome fish).......You could check out rainbowfish too....They would fit in well with barbs and a rainbow shark........Maybe a gourami, but if you get tiger barbs, i wouldnt get a gourami......Tiger barbs are notorious for being fin nippers....Look at giant danios, they would also make a good tankmate for the rainbow shark........Hope this helps you out and good luck with your fish!
The shark for the lower levels, a school of barbs of some sort for the middle, and some danios for the upper levels would make a nice Asian biotope tank.
Just for reference, rainbow sharks are cypriniformes, not catfish.
