He only had the bad photos of the Button Polyp, and the Homotrema Rubrum so they are the only two we know. The green sponge thing, the brown thing, the tube/leaf looking thing are all new. Also the last one is a white grayish sponge looking thing and it is growing across the rock. I am not sure how to describe some of these things nor the lingo. Give me furry kids or football and I am good but the aquarium stuff I turn into a dumb blonde. I wish they had a class Salt Water Aquarium 101.
