I put a bubbler in Sylvia's tank after reading about them on here. She was fascinated at first and seems to enjoy it (I think). It's one of those thin blue brick-style kinds. I noticed yesterday a chunk was taken out of it - and am assuming she is gnawing on it.
The beast! Should I remove it? Is it safe for her? I almost bought the flat disc shaped one - may have to replace it with that kind instead.
