 |  Help My Blue Tang is Loosing color at Night
Hi,
I'm new to the hobby have had a 55 gallon salt with two clowns running for 2 mounths. Just added a baby blue tang and I came home yesterday night at 11:30pm and saw him wedged in the Blue Ridge coral. HE LOST HIS COLOR AND WAS AN OPAQUE WITISH BLUE AND HIS BLACK WAS GREY. i worried he was sick but the next morning he had his beautiful blue color again and eat very well. But tonight i noticed he lost his color again and was on his side on the crushed coral bed under a piece of dead coral on his side and then he went back to wedge himself in the Blue ridge. I think he is sick or is this normal What should I do. It is not marine ich I know what that is and have been through it before . I also have a my saliniety at 1.180. I know bule tangs esp. require prestine water conditions and a rigid diet. I think he will pass IS THIS NORMAL. WHAT SHOULD I DO PLEASE HELP ME I DONT WANT TO LOOSE THE FISH. Thank you to all that reply...... |

Sounds strange to me.
Are you sure about your salinity...should be 1.022 - 1.025 yours would be way too high at 1.180
If he looks good during the day and eating he must be OK.

At night or if the particular fish is scarred, often times you will notice that certain fish will have a different color scheme, that will correct itself normally in due time. _________ 125gal.w/Mag9.5 return(dual megaflow)>Mag7 pump Aqua Cev180skimmer.Wave2k Hamilton Reefstar(2)250watthqi(mh)pend.a Yellow, Naso Tang Red Lip Blenny Percula Clown Demoiselles Niger Trigger F.

I think thats normal. My yellow tang and green chromis also lose color at night. My tang becomes a light yellow/white. And my chromis lose some of the green. Dont worry about it.  _________ 90 gallon tank with center overflows, 44 gallon custom sump/fuge, Tek T5 retrofit 4x54 bulbs, Reef Octopus nw200 protein skimmer, Iwaki WMD40RLXT return pump (changed to panworld 100pxx),Knop c ca reactor, PA light house controller.

I would not worry. At night regal tangs, along with many fish, lose their color. Your fish losing its color and wedging itself in rocks sounds normal...mine did that also. As for your salt...when you say your salinity is 1.180 do you mean your specific gravity? If so, I would highly recommend that you lower it to 1.023-25. _________ Tank Specs:
55 Gallon Mixed Reef
48" Tek Light: 4-54W T5 HO Fluorescents
Bulbs:
1 x 54w Fiji Purple T5 HO Fluorescent
1 x 54w Super Actinic Blue T5 HO Flourescent
1 x 54w 14000K AquaBlue 75/25 T5 HO Fluorescent
1 x 54w 10000k AquaSun T5 HO Fluorescent
Hard Stuff:

At this point I would not worry. Our Yellow Bellied Hippo Tang does the same thing. When the lights go out and he is resting in the same place, lying on his side, between two pieces of rock, he looses a fair amount of his deep rich blue, so does our Kole Tang... _________ 72 gallon bowed 150lbs LR 60 lbs LS
