Hi - new to all this and wonder if anyone can help me. I recently inherited a tank with a few fish in it (previous owners left it behind!) Have had all sorts of problems with it, now hopefully under control, and all bar 2 of the fish died. The only fish in it for the last couple of months have been one pleco and one guppy. There has only ever been one guppy, never a pair. Tonight I have a tank full of baby fish! Presumably they are guppies? (tiny things, some with white bodies and some all black). I'm a bit mystified & have no idea what to do with them! Any help appreciated! Thanks.
