Yeah, the 2217 is on the 46gal. I've got an XP4 and an AquaClear 110 on this tank for now, though there's an XP3 sitting beside me ATM that I'm going to replace instead of the AC 110 whenever I get around to it (need some more media first).
I really think that a lot of the diseases that have entered into LFSs originated with how prevalent it has become to import Asian stock. 1) fish over here have no natura immunities to those diseases, 2) the way those fish are mass-produced it makes for weaker genetic stock and the spread of diseases rampant throughout the populations, and 3) the trip over here weakens those fish that were healthy so they manage to pick up everything else they might not have started off with.
That stuff gets into LFS tanks- which are consistently full of an ever-rotating population of fish and rarely broken down and sterilized, infecting population after population of fish- and IMO it's amazing that any stock survive at all.
