Niger Trigger trouble

[Deezreef]

I have had a Niger trigger for close to 1.5yrs now. Up until now he was a model citizen, but has become somewhat of a bully. He will not let the the other fish in tank get to seaweed and I have tried all sorts of tricks, placing rocks in caves, ripping the seaweed...........
Any ideas what I can do to combat this, if not I think I may need to remove him.

While niger triggers are on the peaceful side for triggers, once they start to behave aggressively they rarely get nicer.

There isn't much you can do....Triggers can snap at any moment lol....I suggest removing him.

Anyone in the Orlando area want a niger trigger? Swap for a frag or two?
