First timer with a clarkii (odd behav.?)

[OCDP]

nice! either way, african or not... they are awesome.. I like the colors of clarkii.

that's a nice tank you have.. or one of many nice tanks? haha.

what is that stuff in the bottom left of the picture? It's green and leafy and is infesting a zoanthid rock of mine, with another type of green stuff. Mine isn't nearly as long, but it grows like a weed so I keep picking it out.
