I got this free from my LFS. They are relocating, so they gave it to me, lol. I initially liked it because I wanted to get a fan worm for my 24g and the dead coral base looks like a dead tree stump. Upon placing it in the tank I noticed so.e Coralline algae and what appears to be orange sponge? The next day I noticed so.e small polyps on top and around the base. They don't look like typical Aptasia, but I'm still new to corals and such. Any inputs on what things may or may not be is appreciated. Hopefully pics are viewable.
