Tank 1 - ex CPD
So, some days on from the poisoning debacle I've had a test fish in there for a few days and it's behaving normally. The snails seem to be finally normal again too, they are moving about and eating. Test fish is a large female fighter so she is pooping enough to help the filter get back on it's feet if it wasn't functioning. There is a little carbon in the filter as well that I will take out in a week or so before putting fish in.
Tank 2 - erythromicron
Still no fry appearing from here, I would have thought they would have emerged by now if any were there hiding in the rocks. At the moment I am assuming the stones method was also unsuccesful and over my 3 week holiday I will have a poke around in there and see if any turn up.
