I have recently purchased an African clawed frog and I am qquite concerned about its health. I have heard you need to use fresh water for its tank but I have been using tap water. My frog is a male and he seems to be functioning perfectly in ever way apart from the fact that he has stopped growing since we have used tap water, when he is fully stretched out from head to toe he is about six inches, is this normal size? And do I need to use fresh water rather than tap water?
Please help.
