Another ID question, and they aren't deer antlers
 Those black things that look like antlers. Some sort of sponge? Another shot  They are black and not blue.

Sponge would be my first guess also but it could be a Codium species of algae.

Sponge. I have the same thing in my tank. Sometimes when I use a power head to get the detritus off the rocks I'll break a few off, but they always seem to come back.
