I acclimated our new Royal Gramma's today for an hour before putting them in the tank (as told to by etropicals.com). They have been in the tank now for 4 hours and they still aren't swimming around. They're still in the "hybernation" state that they came in. When they first came I really thought they were dead, the didn't move AT ALL. etropicals said this is common & it's a hybernation state. Anyway...shouldn't they be swimming after 4 hours? How long does it take a fish to get used to a new tank? They are the only fish in my 80 gallon tank.
