Hippo tang ?

[jhill5]

I have a blue hippo tang that is getting darker and darker, almost blacl with some blue spots. It seems healthy, it is eating and swimming, but I am not sure why it is getting darker.
It is in a 180 with a yellow tang, GSM clown, and 3 green chromis.
Any ideas?

How long have you had this fish?
Can you provide a picture possibly?
What are your water parameters (ammonia, nitrite, nitrate, pH, kH, salinity, and temp)?

I am at work so no picture, plus he is a hard fish to catch. He is a very dark blue almost black, with some lighter blue on the sides. I have had him for about 3 months.
sal 1.0245
amonia 0.0
nitrate & nitrite, blue is zero,the orange is 10
PH 8.2 - 8.3
calcium 380
temp 78-80

Has anything been added to the tank recently?

the chromis were added about 1 month ago, I can not imagine they would effect it. I also had a clam die about 6 weeks ago and a small amonia spike from that, but he was dark at the point already. I am getting a Naso tang today, but it will in QT for 4 weeks. The Hippo seems fine, just dark.
