Well, FWIW, the Allardi are now in a QT along with the Black Ocellaris (and the FEMALE CONTINUES to be ICH FREE)...moved the 17 day old percs to a breeder net. Things haven't gotten worse, but they haven't gotten any BETTER either. I'm going for HYPO salinity for starters (so far down to 1.017...will probably drop to 1.014 tomorrow and *maybe* go a little farther, we'll see how they react), will probably combine with daily 50% water changes, still up in the air on meds. Also up in the air on what I'm going to do with the rest of the fish in the tank, but I DO plan on continuing with the Ruby Reef Kick ICH dosings.
For what it's worth, at the time of posting, the fish look better than I've seen them in weeks. I believe most of the ICH dropped off them today, but again, I'm not talking about "looks" as in physical appearance so much as "looks" in terms of behavior....they're alert, active, so far the move to QT has been a good thing (surprise surprise).
The battle plan keeps changing by the day as things progress (or don't!).
