I know some people like the concept of a "centerpiece" fish, but I'm not. Virtually all fish live in schools or shoals or groups and to isolate one of one species is not, in my opinion, appropriate. We all know that tetras and barbs do best in schools in our tanks, as do most other fish. So why isolate one of a species? Our fish are social creatures and should be recognized as such. I firmly believe that fish are healthier, behave better, and, although this is a stretch - happier, with others of their own kind.
