I've been having a problem with my fairly new tropical fish - a few have died and speaking to the shop it would seem I was given wrong advice (by them) and have fish which aren't really compatible.
Now the numbers have become less, the fish are becoming aggressive. The advice from the shop is to let the numbers of the incompatible ones dwindle naturally, but I can't sit and watch them harass each other to death, it's horrible.
So if I turn up at the shop with the incompatible ones I've got left, will they accept them?
