I realize the term pineapple sponge is overused in this hobby but when I search types of sponges, the image that comes up most often looks exactly like what I have in my tank. My 150 gallon has been set up about 3 months. I moved a lot of LR from my old 55 when I upgraded. Noticed a very few of these sponges when I was moving the rock. Now they are EVERYWHERE. I guess it had something to do with the move. I know they aren't bad for the tank but the are starting to be an eyesore. Whats eats these things?
