Well I'm considering what I want to do with my 75 gallon tank. I LOVE tiger barbs but everyone tells me they must be kept in just a tiger barb tank. I would be willing to do that but I would like to have a variety of fish. I was thinking of adding 6-8 tiger barbs, 3-4 silver dollars, a red tailed shark (I've heard differing opinions on whether they are schooling fish or not as well). I also want to have either a pictus catfish or cory catfish but do not know which would be best in this setup. Anyone's opinion on what I am planning on adding because ofcourse the fish store just says "it all depends on the individual fish on how and what you can add".
