I have an algae bleeny that is relatively new (about 3 weeks) to my 55 gal reef set up. She's been doing great after settling into her new environment; eats often, and is very inquisitive. She'll watch you as you go around the tank, and follow you.
But today I noticed that she was just sitting on a rock, and not moving around as much as usual. I have seen her nibble a bit at the back of the tank. Should I been concerned? And if so, what could be causing this new behavior?
