Oh well I thought he was dead so I took his shell out and got a peppermint shrimp and I'm pretty sure it killed the crab :/ and no the biggest change is the peppermint shrimp and weekly 25% water change, it was looking normal when I first got it then it spilt like that, it has two mouths now and that bubble separates them,my toadstool/leather I'm not sure of the name but it has been molting for about a week and the it's splitting into two stalks I'm hoping that's what the frogspawn is doing but it's been weeks
