Those are some sweet fish, but isn't there something to be said about showing off a single species, and even a single locality.I personally appreciate this single species tank idea. this may have rubbed off from keeping frogs, but i think it applies to fish as well. both of my tanks are single species. even community tank are best single species. For example a big group of tiger barbs looks better than a cluster**** of community fish. It also is probably best for the fish. Any thoughts?
