I realize i have posted another thread about this but i am worried. My clownfish is breathing heavy and not swimming as much or being as active. I have heard it is my filter but that does not make a whole lot of sense since the clown has been in the tank for 3 years and has not had problems since a few days ago. Everything else in the tank is fine except the clown. I will get parameters for my tank as soon as my tests arrive from amazon.
