hi...my black moor seems to just float around under the surface of the water...he swims fine when i feed them and he also plays with me when i do water changes...is he fine or is something wrong ....i see all of them floating around at the top just under the surface from time to time but he does it more than the others?? my tank temp is 77degrees farenheit..the water parameters i just checked and are
ammonia- oppm (its still yellow with a slight greenish cast..not quite .25ppm)
nitrite-0ppm
nitrate 20ppm
ph 7.5
so what do you think?????
