We're just looking out for you and your fish. I was going to put a tusk in my 90, but decided against it due to tank size. I know you don't wanna buy a fish just to have it die because of stress. IMO
, the tusk will be fine in the 110g. And if the 110g is 6', your tangs outta be good too. I have heard of Lion fish eating clowns. Anything that will fit in their mouth, they will eat. If you do get the tusk, please post pictures! Imma get one for my 180g.
