Ok thanks I'm looking at that website as I type! By the way right now I have a 3-spot gourami, some platy, guppies and redeye tetra. Not all in the same tank. I'm trying to figure out how I am going to group them and what other fish I should get. The tanks are 20 and 29gal. I'm thinking swordtails, mollies, diamond tetra or dwarf rainbows although I can't seem to find any other than Australian rainbows.
