Hi. I am setting up a 55g tank and wondering if my 3 favorite fish species from past tanks are compatable in both water conditions and temperment. I would like to get 6 - 12 cardinals, 2 tin foil barbs, and 2 firemouths. My trusty (but very old) aquarium guide says both the firemouth and the tinfoil barb are peaceful, but maybe times have changed. The tank has many caves and hiding spots, but I want the cardinals to be able to swim in schools and not get chased constantly. All would be purchased as smaller fish, maybe there is an order of introduction that would be better? thanks
