Red spots on fins and red outline on mouth

[michael1974]

I have a problem that has cost me three fish in three days. My yellow tang about 4" developed some red lining around it's lips. It died two days later. My tomato clown,about 2" developed some red splothches on it's pectoral fins and tail. It died a day later. Neither would eat after developing these symptoms. My 2" coral beauty died the night my clownfish died. It,however had no visual marks or blemishes of any kind. The other two tank mates are a marine comet,4" and a Niger trigger,4". The trigger is very passive as is the comet. I have just started the Aqua Bella bio-enzyme treatment earlier this week. My water parameters are excellent. Nothing is elevated,in fact the ammonia,nitrates and nitrites were zero. My ph is 8.4 salinity is 1.022,temperature 75 degrees and steady. I would appreciate any advice I can receive. Please help as I don't want to lose anymore fish. I am close to giving up completely.

It sound like a bacteria infection you would need to move your fish to QT to treat. Treating in DT is ill advised, rocks will absorb medication and make it ineffective also some medication will kill inverts.

Thank you,Mr.Limpid. I lost the three I mentioned. The other two,comet and trigger are fine. No evidence of any malady. Thank you for imput. Wish I could have saved these guys.
