Small file fish in fron of an nocturnal sea pen. These file fish are everywhere and are extremely diverse. I love these guys, super cute. The sea pen rises up from the rocky, sandy substrate that is Secret bay. During the daylight hours there is nary any kind of seapens or soft coral present. A half hour into the evening the start popping up everywhere.
This sea pen was a symbiotic
condo for shrimp and crabs as well.
