Ive had my Emp for 9 months now. I have him in a tank that measures 2 feet long 1 foot deep and 1 foot high. I think its a ten or twenty gallon. Anyway ive had him in there for 9 months and he has never even been to the other side of the tank. Hes never left more than a 3 or 4 inch perimeter from his hide. I know emp hide alot but he never has even been out. Could i just put him in a 2.5 gallon seeing that he only uses a few inches? Is this abnormal? He recently molted and still he has never been thru the tank. any help guys? Thanx.
