At this time i have a 3 inch Undulated in my 30 gallom with a percula that lives in a long tenticle,a blue damsel, and a large manderin dragonet.there is a ton of live rock with plenty of places to hide and keep his interest when he is not using the serpent star for a toy.at this time the percula is the meanest fish in the tank by far very territorial however if i dont get another tank set up soon the undulated will be the only one in there.I have a 150 with 2 volitans,2 triggers,2 medium angels a huge red corris wrasse,and a zebra morray.I just cant get the nerve to put him in there till i set up his own 90.see ive kept fish for 22 years breaking some rules along the way,the undulated has always been my favorite.it is true some triggers do have there own personality and act totaly different then they are supposed to like my little guy but realize this the best behaved undulated even years down the road will one day go physco and usualy its only a couple of weeks.Honda12;381845; said:Has anybody succesfully kept an undulated trigger with any tankmates. I am planning on getting one, but, I read that that are highly aggressive to other fish. So has anyone kept tankmates with them, and if so what.
Also is there any fish that you think might stand a chance with one and that I should give a try, as long as it is not to expensive.
