I woke up this morning to find that both of my clownfish seem to be abnormal. They are swimming very close to the surface instead of their normal behavior of staying below. I was assuming that maybe the oxygen level was low so I put it a couple small air stones to re-oxygenate the tank which is only 42 gallons. All my levels seem fine and all of my coral is in fine shape. I took a picture below of my black clown since he is losing his color fast. What should I do?!?! :help:
