It doesn't matter now. She's gone. I've had her for a long time.
I do keep the water in pretty good shape. Last time I did a PWC
and checked perameters, the nitrates were at 40. Everything else is good so I'm not sure what the problem is. All the other fish, anemone and corals are fine. I'm making more water now for a 30% water change to get the nitrates down.
Actually, about a month or so ago, the temperature dropped to 73 before I noticed that something had killed my heater. I immediately got another heater in there, but it took a little while to heat up to the normal temp. At that time, Dori did not look good. All other fish were okay. I could see Dori's ribs after that for awhile, but have been feeding them all normally and since she'd been eating like a pig, I thought she was okay. It could be she just didn't do well with the temp drop. She never did fatten up after that. She was fine before that as far as I could tell, but I had never noticed her ribs showing before that temp drop. Maybe this could be the problem???
Anyway, I will get my nitrates down, get the QT cleaned out and started up again and see if I can find another regal tang at some point. I'm certainly not very interested in looking at new fish at the moment, but I know I will want to soon.
