So its been awhile since ive posted any updates on my tank, theres a reason behind it. As some of you know i had a blue tang that contracted ick. I went the hypo salinity method. Was able to lower the salinity and keep it there for a month or so. It looked like i was able to get rid of the ick. I slowly began to raise the salinity back to normal, when one morning i awoke to find almost every fish now was extremely salted with ick. All this effort for nothing, so i wasnt giving up so fast. I decided to treat with copper this time around, but i had all kinds of inverts in the tank that wouldnt be able to handle it. I had a spare 30 G that i decided to set up as a hospital tank. Well i was able to transfer all fish and treat with copper but it was too late. I think i actually just stressed the fish out even more with the transfer and the copper. One by one i lost every fish i had, what a sick feeling. I'd say i had over 300-400 worth of fish, all gone. With all that said, ive kept my protein skimmer, emperor 400 hob, live rock and all the snails and crabs running in the tank for the past 2 months. Im guessing its safe to say that the tank is ick free being that long without fish. So my questions are: with no fish being in the tank that long, has it affected my bb? I checked the parameters today and everything cleared out to 0 except for nitrates which read less than 5. Ive occasionally added shrimp pellets for some of the snails and crabs to snack on, but thats it as far as anything goin in the tank. Will i see some sort of cycle when i add something to the tank? Im looking just add one decent size fish that can live in a 55 for life by itself instead of a community like i had started in the first place. Is there any predatory fish that i would be able to house comfortably?
