i have five enigmas. i have seen one circle but only when she gets stressed from misting her and only sometimes. the rest have no issues. i mean they are enigmas so they aren't quite right , like they like to look at you but other than that no visible issues thus far. my oldest enigma i got in 2007 and i think was a 2006 hatch has never exhibited any problems, other than him loving to look at you heh.
also she's off food right now, she hasnt been eating for a week , temps are ok, (90-93 on hot side) maybe because of the winter time, shes actually 47-49 grams
this little guys are the offspring of my tangs, they hatched on june 13 and 15, one's actually almost 90 grams today! lol his dad is weighting 100 grams and measuring 25 cm, what ya think? possible giant?
