I got a Toadstool Leather (Sarcophyton sp.), which was incorrectly labelled at the LFS as lobophytum sp. Anyhow, it came with an add-on, and I am wondering if this is a different species or if this is what a juvenile Sarcophyton looks like (I doubt that.). Thanks for ID! As you can see from the picture, my Flame Hawkfish is also wondering...
