well my ungulate triggerfish does that to but i cant really do anyhting about it becasue if i move it back to level he will jsut move it back to what it was at so i just leave it alone cause it is what he likes
a huma huma would be food cause they can get along with alot of other aggressive fish but if you go with something like a undulate you cant really have them with anyhitng else
i am going to set up a 90 gallon tank with an undulate trigger my question is what is the bigest size of undulate could i put in it and what is the bigest undulate you have seen at your local fish store :confused:
