Hello RC
My yellow tang has been in my tank for nearly 6 years, and he rules my 180g. He eats like a champ and appears healthy as can be.
Over the past 2 days he has developed an orange 'flush' to him, along his top, bottom and near the tail. His behaviour remains normal, and he is eating just fine. (I feed nori, NL pellets and a frozen blend including PE mysis daily)
I have done some research and found that this is most probably due to stress, or poor water quality.
The only thing that has changed with the system in nearly 4 years is that on Jan 19th I removed my sump, sectioned it to include a 3rd chamber where I added about 2" of additional sand and one large piece of dry rock. I also redid my under tank plumbing. Everything cured 48 hours before reconnecting, and I used the same aquarium safe silicone that I've used in the past.
I have tested parameters daily since the changes, mainly watching for ammonia. Current parameters have been consistent, and have been consistent for a long LONG time previous:
ammonia = 0
nitrate = 0
dKH = 9
calc = 440
mag = 1300
sg = 1.025
temp = 79
All my other fish and inverts seem just fine, and corals (leathers/softie tank) sulked for one day but are now acting normal, though my toadstool only has partial polyp extension (but he's a grumpy grump and often does this even after regular water changes!).
I can't think of anything I should do different and am figuring to just keep things consistent and let it run it's course, but I wanted to run it by RC as well in case I'm missing something.
