I have a 90 gallon cycled tank that will soon be the home of 3 small angels and 1 pleco. I am looking for ideas on compatible tank mates for them. Maybe a school (9-10) of brightly coloured smallish (1-2”) fish would work? Or more angels? Or some kind of centrepiece fish? Also this move leaves my 15 tall empty. For it, I like the idea of tiger barbs and cories but with the tigers being fin nippers I’m not sure if it would fly. What about an algae eater for the 15?
