1 of my corys is acting strange. it perches on the leaves of plants, and is a liitle darker in complexion and skinnier than his tankmate cory. I know that i feed them enough. It is breathing kid of shallow. It doesn't have any other visible symptoms. Ammonia, nitrite good. Ph 6.8-7.2. And hardness and nitrate good. I have a hospital tank, aquarium salt, and some medicine i can use if needbe. Please respond soon, so i can treat it if necessary. Thanks.

do you have a air stone in your tank? it may be from not enought dissolved oxygen in the water or bad quailty water. how many and how much water changes do you do? Does it still swim and eat? is its behaviour any different then before it started doing this? Does it hide?
