Update and request for disease diagnosis. The triggerfish has now been sick for 20 days. It just sits or hovers, sometimes in the rock work, sometimes above the sand bed as in photos. It won't swim and it won't go after food. I can feed it by taking lrs fish frenzy with a tweezer and sticking it right in front of its mouth. It just takes teeny nibbles. I just fed it a piece it would have devoured in two bites before that took him about hundred nibbles to eat half of.
The physical manifestations come and go. I finally got a pretty good photo of one side of the fish. You can see white spots, and some white spots on the top of the trigger. There have been times where there has been very little. You can also see some fraying on the tail and dorsal fins.
I treated the whole tank with flucanazole tablets at does of 1 tablet/10 gallons thirteen days ago. Didn't clear things up, don't know if it helped. (Did nothing for my algae, bummer lol). I tried once to catch it and do a dip as Dong recommended above. If people think it's a good idea, my son is home tonight and we could probably get him out if he's not in rock work.
Do people still think this is fungal or is there another possible diagnosis/treatment? If I can catch it, I can easily set up a 40 breeder hospital tank if there is some recommended non-reef safe medication.
Thanks in advance for help. It seems a saveable fish. Oh yeah, there are 14 other fish in the system and they have shown no symptoms or strange behvaior. It seems completely isolated to the trigger.
