Ok looks like I'll just be cleaning out urates whenever they appear. On the issue of cleaning: should I change the water every day or every other day?
I like that Salsa bowl idea! I'll get a couple of those (I have a dremel I can use for this too) to test out his affinity for the moss hide and see if he's properly regulating or not. Much less expensive than buying another rock hide to test this out. Thanks!
