Hey everyone. I just started a 20 gallon FOWLR. For now I only have an Ocellaris Clownfish and 4 Blue Legged Hermit Crabs. I just wanted to ask...is it normal that my clown usually stays in the same corner of the tank close to the glass? He does swim around the entire tank but spends long periods of time in the same corner. I've had him for about 3 weeks now and he eats very well and looks very healthy. Could he be hosting the glass? Lol. Sounds silly but I'm still curious.
