Eh, first post on here, hopefully i can get this little guy cured. Anyway I'm very new to the world of marine fish keeping and my fish is acting odd. My tank is newly cycled, and I just got my first fish a couple of days ago. I had a few inverts in there as well and they are doing great. but my ocellaris is acting strange but then again it could just be me over reacting because i have other freshwater fish that i am treating for hexamita. he seemed healthy and happy when i got him. he is maybe an inch and a half long, and a few days ago i noticed a perfectly round pink spot on the side of his head. he was also breathing heavy, so i did a water change and that slowed the breathing down some but he still had that spot and it disappeared yesterday sometime. and he was breathing heavy again, so i just treated it as maybe he is just stressed from entering a new tank. but now he is hiding, his colors are fading, he is at the bottom of the tank, and i can see straight through him, literally. he is so malnourished, which is odd because i feed my fish on a schedule, and he looked plumpish yesterday. I will post pictures and more info tomorrow but for now you'll have to go off of the evidence i have given. Any insights are appreciated.
