Ok, thanks, looks like I've got a bit of a wait ahead of me then, she's fat but she doesn't look like she's about to burst or anything! She was behaving strangely yesterday, she spent alot of time sitting on top of the filter which is not like her at all. Today she's almost back to normal, poking about in the gravel, looking for food, she still isn't chasing the Guppies again yet tho! This seemed to be her main form of entertainment - poke around for food - chase guppies - poke around for food - chase guppies.........
I know she'll eat her own fry but what about the other fish, are they in danger from them too? I have guppies (obviously!) Neon Tetra, a dwarf Gourami, Bumble Bee Goby (don't tell me about brackish water, I already know) and a bristle nose catfish.
