Thick white poop hanging from clownfish

[Tobias9413]

I feed once a day. I have been giving them frozen mysis shrimp and make sure to thaw them in the tank water first. My other clownfish is doing fine but this one i noticed is breathing a bit heavy and not as active. Should I stop feeding the mysis shrimp?

Tank levels are fine. Ammonia, nitrate and nitrite are all at 0 and ph at 8.2 Temp is at 79

Is that all you have been feeding them? It's better if you give them a varied diet.

Your fish may have internal parasite. You can treat it with a product called PraziPro. You may want to set up a small quarantine tank so you can treat the whole quarantine tank water. You'll want to also soak its food in it for a direct treatment delivery method. Good luck .
