A few months back I posted up some photos that I thought were algae. A few R2R members IDd them as sponge. Today I saw a thread about aiptasia and got a bit freaked so I'm posting up a few new images. Want to make sure I'm not dealing with something troublesome. I managed to remove one piece of rock and scrap off a small bit for closer examination. Also one shot one shot of some of the stuff in the tank.


They come in all goofy shapes colors and sizes
