Bicolour Blenny changed colour

[peter fumo]

I have 2 very healthy bi color blenny bought months apart from different places. after each of them were in my tank for a few weeks they turned all black.

I had the same happen with mine. And all 3 of mine are eating corals, so I will go fishing for them as soon as the micro hooks arrive and then they will go back to the fish store or into exile in the coral free sump tank.
