Hmm, well, good to know that they would be ok with the fish I have now. I haven't had nipping problems with my danios. Jasper seems pretty peaceful, too.

So can the 8.0 pH cause them to die? I guess I might just look at getting different fish instead. Suggestions for flashy, brightly colored little schooling fish that would be compatible with mine and be ok with a pH of 8.0?
