I have some a Hellfire Torch, Hippy Trippy Mushroom, Radioactive Monticap, Fire Finger Digi, Blue Hammer, dragonsoul favia
Haven't noticed any problems from either the Mantis' or the Bobbit. One Mantis even punched a snail right like.. between the tentacles of the Hellfire Torch, I got worried and moved the snail away. Turns out there was no damage to the coral from the inadvertent effects of the shockwave and heat of their punch. Fascinating.
As for a video of it eating, that will be my next attempt lol! Statly tuned
