So my tank is newish...started middle of April. 80 gallon "cube" star fire glass tank from SCA. Mixture of live rock from LFS and base rock. Two 360we Kessil Tuna blue lights, octopus skimmer, tunze return pump. Using a filter sock with carbon depending on circumstances. So I tried to QT everything AMAP....fish with copper power for 45 days, metronidazole for 10 days for worms. Everyone lived except for one tiny jawfish that was basically DOA. Now slowly over the last week all fish moved to display tank, after being symptom free the whole time. All was well for a week...then suddenly two days ago my two spot bristletooth tang has a SPOT. Eating and moving well, very occasional flashing. Only one being bothered by the spot is me. Day 2 first spot is gone but another 2 on the other side noted...dang! Fish still acting normally. Only one being bothered is still me. Day 3, today, all spots gone...fish still acting normally, only one concerned is...you guessed it, me. Looked like ich to me. But does my tank "have it" now? No other fish show any signs. What about adding anything new? Really confused.
