Well...I'm not sure whether anyone will be able to help me out with this, as I suspect it may have to do with certain things I can't control (more on that). But I thought I'd give it a shot anyway, as I'm grasping at straws at this point.
I maintain the aquatics (fresh and salt) systems in a LFS, and for the most part, things run well, despite some not-so-minor systemic issues (largely out of my control: nonfunctioning skimmers, massive uncontrollable salt buildup, constant movement of fish in and out of the systems, no QT, no proper acclimation - float and dump -...I could go on. :doh:). I have two saltwater systems, both ~100g, each on its own isolated sump, one system "reef" (inverts, occasional corals), one system FOWLR. The "reef" system is, for the most part, good - the fish tend to do well, as do inverts - corals are another story, but that's a lighting issue.
The FOWLR system, on the other hand, is driving me up the wall. My problem is this: I have a massive mortality rate in the system, especially with my clowns. At any given time, I typically have ocellaris, maroon, tomato, and clarkii clowns, and none of them does well, esp. the tomatoes and clarkiis. Basically if I don't get them out of there within a week, they're goners. Other fish in the system - squirrels, triggers, cardinals, blennies, damsels, angels - do well for the most part. Some (TANGS) don't, but they typically present with ich and can recover.
I have no idea what's wrong with the clowns - they don't show visible signs of ich, they're not getting beat up on by other fish, the water parameters are acceptable (never as good as I'd like them to be, but within what's usually considered the "safe" range), I keep the system at low SG, ~1.020, as there are no inverts present, and I've had so much trouble with ich. I'm not sure what I'm doing wrong, but obviously it's something, because they never seem to last long. In the other salt system, I have snowflakes and saddlebacks, and they do fine. Leads me to believe it's something in this particular system, not a husbandry issue, but I haven't the foggiest what the problem actually is.
Any suggestions, questions, help, etc. would be helpful - plus, you'd be saving the lives of countless clowns!
