Is it really alsways necessary to get 5 or more of certain types of fish?
I'm speaking specifically concerning rosy barbs, rainbowfish, odessa barbs, and the like. These fish get up to 4" or more. Once you get 5 or 6 you are up to 20 - 25" of fish. That one species by itself almost maxes-out a 29 gallon aquarium.
I just purchased 8 dwarf neon (Praecox) rainbowfish. They only get ca. 2" so I'm up to 16" with them. I got 3 males and 5 females.
