Had two rams for about 2 weeks now, but one of them seems to be acting strange now. Its been swimming near the surface, breathing rapidly. the tip of its mouth seems to be narrowly touching the water surface, and it makes a 45 Degree angle with the surface and its body. It started doing this about 2 days ago, so im not sure what could be happening. Parameters are fine, ammonia and nitrites at 0, nitrates less than 5 PPM. I havent really noticed anything else wrong with it or the other fish in the tank. Its colors seem a bit faded though, could it be stressed for some reason? The tank has plenty of plants and several floating plants for it to hide.
