Hi everyone, I got a 175l marine tank, with two cleaner shrimp, a royal gramma and two clown fish. All my water levels are fine, but one of my clown fish is going to the surface of the water, it has no signs of burned gills and has no spots, what could be wrong with him? I have two power heads and the tank has been going for 7 weeks, and the fish have been in there around 2 and a half weeks.
Thank you in advance
