I was joking about the Aimara Wolffish not having teeth, or attempting to bite when a hand reached into the water to retrieve the net on the bottom. I'm gonna go ahead and bet that the fish in the video has teeth about 3/16" to 1/4" long already and that it's going to use them to try and bite whoever or whatever goes into that aquarium to retrieve the fish net. 100% positive. Sorry for the confusion. Good luck. Mine is pretty aggressive also, but I try not to taunt it for the Wolffish's safety. They hit whatever it is they are after so hard ,that I don't want to chance ANY type of injury with my fish. I like my specimens to be as 100% perfect as I can get and don't want to do anything that might cause that 100% number to be any lower. Once again, I apologize for my comment and sorry to confuse anyone. Thanks.
