We have promised DD (5) some fish and know we want tropical fish but I'm not sure where to start.
We used to keep koi and goldfish so we are not total novices but in our new house we've only got room for a smallish (although wil obviously go as big as poss) tank.
Any advice? We are ok on tanks, filtration, uv and all that - its more the actual fish to start with. I don't want to get the wrong ones and for them to be unhappy.
