Ok i so i have go a pair of clown fish they are wild court and came as a pair. the problem is that the stay in the corner of the tank if they move from the corner its only 2 or 3 inches and then straight back . the clowns have been in the tank for 3 days now and its the front corner of the tank where there is nothing at all the just sit there swimming with their heads in the corner of the tank. is there a way to entice them to move around the tank a swim around like normal
