Is a 20H big enough for a single angel? If so, how many/what tankmates could go with it? I know the general guideline is 30g but I'v also heard a lot about breeders using 20Hs.
Thats OK then. I've got about 9 danios and 2 cories in there now, the danios might be finding another home (Or might not be there when the angels bigger). I'll look around, I'm going along the rute of having one of two bigger fish that I get to know well. Plus it would go with the planting OOI, how quickly do they grow from about 1.5 inces long to full size?
