Yellowtail Damsel turned black.

Well, I have s few fish in QT. They were apparently exposed to toxins from a Sea Hare. The yellowtail Damsel that is normaly Blue has turned black. He will go in and out of blue to black in a second. Swim around blue, lay there black. Is this odd or what. Never seen this before.

The same thing happened to me when I had blue and gold damsels. Their gold bellies would sometimes almost turn black. I don't know if it is a lighting thing becasue I also had a 4 stripe damsel that would turn almost white in the dark, and then brighten back up in a few minutes after I turned on the lights.
