I woke up and my clownfish was in the bottom corner breathing heavy, it was early so I figured it was still sleeping. However, it hasn't moved from there other than swimming back and forth around my sand for about 5 hours and won't eat. My other clownfish is fine, and my tailspot blenny is fine. I added the clowns a week ago, and my tailspot yesterday. Salinity is 1.026, PH is 8. I haven't tested much else. I don't know what to do. I do not see white spots, other than a small white speck on its lip. It was a lighter color than the other clownfish whenever I bought it, but my LFS said it was just different breeders. Please help, I don't know what to do.
