I think it's capnella, but I'm not sure. It hitched in with this favia frag attached to the epoxy. It was originally about 3mm in length when extended and I had to wait a long while until it was large enough to get a picture and make out what it is. It grew from 3mm to ~20mm in about 2 months. Any ideas? I'm planning on waiting until it's large enough to cut off and thread onto a plug of it's own, before the open brain eats it.
Oh yah, and anyone know how to I could get this favia to return to it's original green colour? lol
