saltwater4ne, please do not give advice on things you know nothing about, (even when you are giving advise to yourself it's false info)
I'll answer the question anyway in case someone really needs to know why, and not think sw4mes BS is what to do.
do not put a queen or any other trigger in with a undulated. Undulated,Queens, and blueline triggers need to be KEPT by themselves, espicialy in a 125 or even a 55G tank (which is too small for a fully grown undulated)..in say a 250-300G system you could do a undulated and POSSIBLY a large grouper if you add the grouper first.
