Black Spot On Rock That Maroon Clown Seem Obcessed With?
Hey y’all. I have a 55 gallon bowfront aquarium with two small lighting maroon clowns a lawnmower blenny 4 chromia and a scooter Blenheim. My one maroon clown seems obsessed with one part of the live rock that’s a big black mold looking spot. Could this just be his territory and where he urinates affecting the chemistry on that piece of rock? Or is it some kind of algae he gets high off of? Thanks.

Need a much better picture but my guess it that it's a sponge.
