Anyone have any clue what this might be effecting my clownfish? A little background… about 1.5 months ago I added a red tail trigger and everything went south from there. The trigger developed what looked like ich. Regal angel also developed same symptoms but not as many or pronounced spots. These spots persisted for about 2.5 weeks until my bimaculatus anthias died, then my regal angel, then the trigger, then my 2 clownfish then all 3 of the disbar anthias. The weirdest part is that my ornate leopard wrasse, scooter blenny, blue cleaner wrasse, and yellow watchman goby all seem to be doing great. My corals also look great and my fromia starfish is still alive. My maxima clam did die though also. The anthias never showed any symptoms of disease and the clownfish looked different from ich… like slime coat was peeling off. My LFS guy tells me that some aerosolized chemical must have gotten into the tank. Did 20% water change and added carbon and poly filter sponge. All 4 fish and corals were looking great for the last couple weeks so I added a new pair of clowns on Saturday. Everyone was fine and eating well until the smaller clown looked like this yesterday afternoon and did not eat. Seemed to be breathing rapidly. Put 8oz of ruby reef rally pro in tank yesterday (too low of a does but that’s all I had 108g tank.) Clown is gone this morning, most likely dead. I’m assuming my CUC ate it because I can’t find it anywhere. Today my other clown has same symptoms but less pronounced and still eating. Any suggestions as to what this might be and what I should do?
