Hello. I have a newly set up tank and started with a filefish. He was doing well for about a month and then we added two clownfish. The tank is 26 gallons. The filefish mysteriously disappeared. Mind you the ammonia and nitrite had been zero before we put the fish in. Two days later one of the clownfish disappeared. The next night the second clownfish died. My dad saw it in the tank as it was dying. It was chopped up a bit by the powerhead. I noticed it looked a bit sickly the day before it died with some white fleshy substance on its mouth.
I am assuming they all died from disease. It just seems odd to me they died back to back. What are some possible illnesses they died from? And what should I do about the tank? Do I need to take it all down and restart? Or is there a treatment I can add to the water. I am not too sure what the next step is...
