What is going on??? This has been happening for two days. I just found it floating upside down in the little swimming pool... thought "this is it" and went to pick it up and its walking around fine. It seems to seizure every once in awhile (I have seen it twice) and then goes so stiff that it looks dead. After afew seconds, it seems a little dizzy and then walks around like nothing has happened. It's freaking me out. WHAT IS WRONG??? It doesn't appear to be eating, but I see it walk around like normal, drink, and swim with it's mate. It also is not as noisy as normal but would appear healthy to someone observing it. Please help!
