My fish are all hanging out in the corner of the tank all day
I have 2 clowns, a blue tang and a blenny. The clowns have been in the tank for a couple weeks, the tang and the blenny have been in for just over a week. I thought at first that they were just getting used to the tank, but they really do just hang out in the back corner of the tank all day. They come out when i feed them and maybe for a minute a day, they'll kinda float around the tank, then back to that back corner. The blenny just hides until he's hungry, but the two clowns and the blue tang just kind of huddle in the corner.
The water temp is a steady 78deg
That corner of the tank is under the strongest powerhead and skimmer pump/intake. The only thing i can think of is that its warmer there. But if the water is 79deg, then why is it such a big deal? Any other ideas?
