Out of curiosity does your fang blenny turn a darker color at night? I just picked one up a few days ago and noticed tonight it sleeping on top of a magnifier magnet and it looked much darker than it is during the daytime. Also having trouble getting it to eat much? What does yours like? Haven’t been able to find too much detailed info online yet.My yellow fang blenny is probably the most entertaining in my tank.
Every time I have my hand in the tank he wants to come hang out on it, and I'm like pleeeaaassee don't bite me little fella
