Octopus Frogspawn Coral (Genus: Euphyllia)

Octopus Frogspawn Coral (Genus: Euphyllia), originally uploaded by tyrsdomain.

This is one guy I haven’t exactly figured out yet…  While similar to the already identified, this one was called an “octopus” coral by the previous owner. However, it appears that a lot of different species under the genus Euphyllia divisia are called Octopus Coral, so that hasn’t helped my research much.

Once I can identify them all, I’ll be in a much better place to solidify their eating habits.  The good news is that this Euphyllia has been growing quite a bit and often extends his tentacles by over an inch, so I’m pretty sure he’s happy for the time being.

Also of note is that he is definitely poisonous to other coral as he seriously wounded our disk coral one day when he inched a little bit too close (they’ve since been moved far apart and the disk coral is doing much better!).
