Yes do not worrie that happened to my frogspawn and it came out of it fine let me just ask you if the heads open up at all. if you can post a pic i can tell you if is doing what mine was doing. basicly it got moodie because i got my params done by the guy at petland and he said they were great. so he just told me to give it time. it took a good two weeks to get back to normal in which this time i started to give calcuim a little more offten.
