I just bought 2 new percular. And, I just add them to the tank yesterday. They don't eat any food that I fed into the tank. But, they eat the foods when they are still at the shop before i bought. When they are in my tanks, they don't eat. What is the problem?.
Also, they seem to swim around the edges of the whole tank non-stop.
