I have had reef tanks for about a year now, and still do not know the difference between these little guys. There are a few distinct types in my tank.....1 is about 3/8" long, curled back...another is about 1/8" long, swimming back and forth, and it's eyes are reflective. The last is about 1/16th of an inch long, and walks around on the side and back glass of my tank. My
watchman goby will pick off the larger ones when they venture too far out from the rock. I was wondering if these are the same guys that a Mandarin would go after. Or do mandarins eat the smaller stuff...Thanks for any input
