Thanks everyone for all your advice.
I've got Mum & Dad back in their own tank and I'm just gunna let them get on with it. If it happens , it happens.
One last question....whats the best way of getting snails out of a tank? :lol: I've heard of putting cucumber under a saucer , leaving it over night and remove it , with snails under it , in the morning. I tried and it wasn't too sucessfull.
I pick 'em out as I see them and I'm removing the snail eggs but I'm hoping theres a quicker way.
