does it sting bro ? just asked, coz one feeding time, the pellet was sinking near the BTA and the firefish went at it. it missed biting the pellet and instead bit the BTA tentacle (yup saw it with my own eyes), after that looked like the fish got shocked, then it sped off back to it's cave, and stayed there for 2 days not coming out as he used to. though he recovered from that in guess, that was about a month ago.
