I'm doing the cleaning daily now, I'll keep up with 25-50% PWCs.
For filtration I'm using an AquaClear 30 on the 20G tank, 2 foams no carbon, inserts were recently replaced. It was cycled in this QT with 5 damsels, and I watched the cycle complete. When I got these tangs, I moved the damsels to other QTs using other filters seeded from this one -- I haven't seen any cycle problems there, though I think the bioload might have increased so maybe that explains the mini-cycle I'm having?
Up until last night I would have believed that he was losing his color due to QT stress only, but now I'm a little more worried. He's still eating, but he's not nearly as active and he's breathing rapidly. I noticed something that looked like ich (well, it looks like freshwater ich looks on freshwater fish -- I've never seen SW
ich before), white spots not on his color like in the pictures. That's mainly what has me worried.
...on top of that, depending on the weather, I may not be able to make it home Tuesday night. I can stop by on the way home from work today to try and pick up some medication but at this point I would have no idea what to get.
