I'd say around a 125, but that combination won't work out too well. Bo

Thanks for the reply Bo, why do you say my selection is shifty? I know that the undulated triggerfish is extremely agressive, but hopefully its genes will be in my favor on this one. If not I will continue my serch. Yet this is still a ways away, just the beginning stage of planning so any more suggestions are welcome. I still have to build the tank

Undulates are jekyll/hyde type fishes. Passive at one moment, vicious the next. I wouldn't keep a boxfish with any aggressive fishes, and the undulate and clown tang are two of the most aggressive species of their respective families. Bo

My boxfish that I have now that will be the first addition to the tank. I suppose it would be a definate problem. He is very agressive to my snowflake eel, wrasse, and pufferfish right now. I am wondering if he will be the same when he is mixed with other large agressors such as himself. Thanks for those replys Fish Boy and Bo, any other opinions and comments are welcome!

In my opinion keeping an undulate in a community means having a bigger, badder fish than him. In the hierarchy of fish there is only one 'ruler' and if it's the trigger your others are doomed eventually. Since you already have the boxfish and snowflake why not try a less disagreeable trigger? Dottybacks and groupers are beautiful too, good for mixed tanks. fwiw
