That's good to know. Mine's pretty heavily planted and lots of places to hide. I'd hopefully get two females just to be safe. I would just be gutted if they ended up fighting or getting stressed out. What did you feed them?
Yeah I heard snails are the main thing they love. I'm sure a place local will give me some and also have fresh bloodworms for them. Thanks for the advice. I feel a lot happier knowing I can provide the little guys a suitable home :-)
