okay, so i just got in from work and saw my 4 inch oscar on the bottom of my 55 gallon tank laying on his side. i don't know what to do. he was breathing really slow, all the test are fine. i thought the water may be too cold so i put some of the cold water in a ziploc with him an set it over in my ten gallon that is usually about 75-80 degrees. the 55 stays right at 68-70. after 20 mnutes i put hin into the tank and he kinda floated a little, swam about four inches and was looking aroud and settled down by the filter intake and is still breathing slow. wtf? what do i do?
