A very interesting read thanks! The advise about moving them to a different tub bigger or smaller each week if necessary, cleaning the whole tub out etc.... A lot of that goes against many things I've read about bp's being upset if you move them, touch them even look at them too much! I would of thought moving them around to get them to feed would make the problem worse ? Maybe not?
I think I will try the leaving to prey in over night next week when I try again .... To be honest there that many options I don't know what to try for the best!
