Ok heres what I know Volitan lionfish, snowflake eel, domino damsel, foxface in a 75 gallon. I explored raw seafoods due to the lionfish at a local grocer. Was feeding the lionfish and eel table shrimp oysters crablegs and salmon. Well I got lucky and they were all eating it fine and everything was swell i was thawing out proportions as I fed them a month or so went by. Well I got sloppy and thawed out a bunch of salmon and placed the chunks in a old sandwich meat container and was throwing it in the fridge afterwards. I usually do the same thing when feeding my other tank with marine cuisine cubes in a plastic cup of water but the unused portion never stays in the fridge for more than 1 day after. Now the good part: damsel died of what seemed to be ich one day (wasnt suprised since he lived with a fish that could eat him) about 2 days later the lionfish died signs of ich and heavy skin loss the foxface started showing weird spots(not like normal color changes)(not bumps) and a small amount of ich and swimming kinda funny (slightly facing down) the foxface is now in a large plastic tub with a piece of live rock and a powerhead being treated with pimafix the eel is fine anyhow I feel like I fed them that salmon that had been in the fridge for several days and made them sick thus causing the ich to outbreak and killing them any thoughts? any thoughts on pimafix Ive never used it? PS my first post hi guys~!
