I just bought a fox face for my 40 gal tank, to help with some hair algae. I acclimated him and place into my tank yesterday. He hid on the side, at the bottom, near a brittle star that hides in my rock. Today, the fish is no where to be seen, and no fragments of him. All I can think, is that my brittle star got him. Is that possible??. Expensive fish food if that happened.
