Eh... that is kinda normal for my Frosted Forest Aussie Lord. Let me list what the central head has caught and killed.
Orange ricordea
Red Interstellar Mushroom
Bristle worms (emphasis "worms" as in more than one... more like more than a dozen...)
Spaghetti worm (I have only seen it once, but wouldn't be surprised if it is more)
Frogspawn tentacles
Blue Effloutanaria polyps
Stargazers (this happened the other day)
Coral Banded Shrimp legs
Coral Banded Shrimp molt
Fire Shrimp molt
Attempted kills
Hermit crab (hermit got lucky. Or smart. Either way the hermit escaped)
Cerith snails
Fighting Conch's snout
Yeah... that aussie lord make my favia, my Euphyllias, and pretty much wvery other coral seem like they are all pacifists. And my favia HAS tried to attack corals, that were thankfully out of its range. But the favia is a saint compared to my Frosted Forest Aussie Lord.
