Seeking real options for my situation. I have a 125 gallon mostly for fish tank (not quite FOWLR as I have cleaner and peppermint shrimp, and some small colonies of montipora, leather, xenia). I had a previous bout with ich. After fish died, tank had no additions for 30+ days. New additions were rainsford gobies and spotted mandarin, no ich. After another month bought my new fish, placed into 29 gallon QT for a couple weeks with Paraguard. Two rounds (first was Atlantic Blue and Mimic Tang and bannerfish, second being purple Tang and Majestic Angelfish (a couple other smaller fish, bluehead wrasse and clownfish that was bullied out of my 55 gallon coral tank as well). Within days of the second additions, boom, ich breakout. Been going for a couple weeks now, I'm feeding focus/metroplex enhanced food, and have installed two in tank UV sterilizers. The only one looking better is the purple Tang, as he was the first to really break out. Putting this many fish into a 29 gallon QT is not an option, they'd kill each other. Putting my angelfish and bannerfish into my 55 gallon coral tank and bringing ich into the tank isn't either. I've considered moving my corals to the bigger tank in the past since the lighting is better, which could delay the potential issue with the angel and Butterflyfish with coral for a time (note they ignore my xenia, gsp, and sps currently already, but my other tank had lps acans, favia, favites, lobo, hammer, frogspawn to worry about, along with the fish in that tank as well). Long story, but what's the best option? Continue with metroplex/focus and UV sterilizers only, or some other option. Also mindful that moving fish and inverts is going to stress out already sick fish. Feeling a little helpless as I watch. Any medication or water change regime that won't kill my inverts worth trying?
