I hope this is NOT an emergency... But!

I have a bright yellow Tang. His face, all the way up to his gills, is looking rather white in color today for some reason. I tested the salinity, and it is good. The Nitrates, Phosphates, pH, and Ammonia are all good. Please tell me what to do in case this is a major situation. I am really worried because I do not want anything to die because of my stupidity. Please help me help him/her ASAP. Thank you! Frog...

 

they lose color after lights out frogfish
they fade and get very white in darkness
or was this seen during a period when the lights where on

what sized tank is it?
how long has it been set up?
what esle is in there with it?

I dont think you have got anything to worry about. All fish lose color from time to time. Steve is spot on with the lights. If the lights are off then Tangs lose their color.

 

I think it might have been the 1-hour of blue light before they went off. -150gals -Been set up for like 2 months now. -I also have a Benny, a school of clown-fish (6), the Yellow-Tang, a bunch of snails and crabs (Like 45 total (10 Turbos; 10 nessariusesses; 25ish red leg crabs), and 4 corals.

 

It was getting ready for sleep most likely.

 

OK good news

its not aggression as there is nothing on that list that would have bullied it which may have also accounted for the fish going pale

I will move this to the Tropical fish section for now
when lights are back on tomorrow, let us know if anything has changed
and we can move back to ASAP if situation merits it

This morning he looks perfectly normal, so I guess I was just being paranoid. Thanks for the quick help & info everyone. Frog...
