Established Koran stopped eating

[owenb01]

I have a 75 that has been up for about 1.5 years and all has been well since about the six month mark. My Koran Angel, which I have had for about 9 months and is about 7 inches including tail, has just completely stopped feeding. A few days ago I broke the tank down to address a hair algae problem and to remove a grouper and a trigger who were getting on my nerves; the angel has not eaten since. A couple of days before that I had added a Moorish Idol, who I thought may have introduced a disease that hit my otherwise healthy Koran. When I introduced the idol, the Koran beat the hell out of him for a couple of hours and I almost pulled the idol out, but the Koran decided he had established his dominance as king of the tank and left him alone. I moved in June and broke the entire tank down then, saved 50% of the water, set the tank back up, Koran immediately resumed eating like a pig. Like I said, however, he has not eaten since this last break down. The idol, on the other hand, has begun eating voraciously, which leads me to believe he has no disease that he could have introduced to my tank. He was QT'ed for a month at the LFS and I checked on him every few days, and he ate there as well. Yesterday, the Koran was very lethargic and showed no interest in food; today he has resumed his dominant behavior but he still won't eat. Other than the 7" Koran and the 4" Idol there is nothing in the tank except a lawnmower blenny, crabs, and snails. Let me take that back, I also have a ton of clavularia, and a decent size frag of acanthastrea echinata. My temperature is high (82-84) but it has always been like this (and the Koran has always eaten like a pig) and my clavularia always alerts me when there is a problem. I recently added some poly filter in a fluval 404 to drop my phosphates. I do aggressive skimming and weekly 10 gallon water changes with RO water. The Koran shows absolutely no outward manifestation of disease or parasite. I am going to try to find some selcon today. Any advice would be greatly appreciated, I do NOT want to lose this fish.

Thanks

good luck ben , i don't want u to lose the koran either. I have a juvi koran I am placing in a 120 in feb. if he makes through the ich he just developed . Good luck I hope he starts to eat . I am sure u have been told to soak food in garlic. If not try that , garlic guard or something sim. I have never used selcon so not sure what it is so if it is the same thing ignore my ignorance.
lucky

Thanks, I couldn't find selcon so I got seachem's entice. I heard garlic will screw up your skimmer. So far it's not working. I don't understand why he just stopped eating.

maybe try some mysis shrimp or formula two soaked in the entice. good luck

I tried the entice with angel formula (which he has been eating since I got him) to no avail. I will get some mysis shrimp today. Does seachem's garlic guard screw up the skimmer or work better than entice? He is still active but is not displaying any of the dominant behavior that is so characteristic of him. I even added some zoanthids to the tank to see if he would eat them. When I first got him he devoured a colony covering a rock that I didn't really care about anyway, but he has showed no interest in these. I will go to any length to save this fish, somebody please give me some more ideas.

I have not read about garlic guard screwing with the skimmer.I have read some up on it and have never read about it causing problems for your skimmer. I just have had a guy at my lfs tell me to use it. I used fresh garlic chopped up very fine and fed that to my fish. Garlic is .99 at my grocery store . I am not saying it will work and like anything else u don't want to overdo it but it did work with mine. Good luck
