Midas Blenny Not Yellow.

[Empty Bottles]

I've had a midas blenny for at least 4 months and he still hasn't stopped using his scared pattern, the most he will do is turn a green, gray, blue(camoflaguing with the rocks and back) pattern when he is swimming around the aquarium. Is there anything I can do to bring out the yellow?

I think you just have to wait and see. He could still be strssed from aclimating or from other inhabitants. Are your water parameter okay?
