Hi All!! I noticed one of my clownfish (false perc -- aquacultured) is starting to turn darker on his top part of the body. by the dorsal? i was wondering what it is.
Tank Params:
PH: 7.8
Ammonia: 0
Nitrite: 0
Nitrate: 20
Calcium: 360
SG: 1.025
Temp: 81
I feed them Spectrum Thera +A and Prime Reef Frozen. He is swimming fine and breathing fine and eating fine. He looks fine but his color is off. is there anything i'm doing wrong?
My tank is a 24g nano with about 35lbs live rock 24lbs live sand, RO/DI water.
Livestock: 2 False Perc, 1 Diamond Goby, 1 Cleaner Shrimp, 3 Hermits, 2 Nass Snails.
also here's some pics of my clown:
