Mixing planktivores - does it work out?

I have a 200+ gallon tank - 72Lx24Wx30H. I have a male blue throat around 5-6 inches and want a male crosshatch. I searched here but didn't find much. Anyone with experience? Other current inhabitants are 2 black clowns, yellow coris wrasse, hoevens wrasse, and algae blenny.
 
I don't know why these triggers (and Sargassums) are considered planktivores. They are pelagic and usually hang around floating mats of sargassum feeding on small fish and crustaceans. (I could be wrong on this, but have seen some papers on the feeding habits of them.)
Anyway, I kept pairs of both Crosshatches and Bluechins prior to Katrina. I lost my notes in the storm, but remember buying the Crosshatches in the spring of 2003 and I already had the Bluechins. So they were together for at 2 1/2 years. They were in a 240 and there were no problems at all. The fact that both were bonded pairs may have helped, but BCs especially are very wussy triggers. I would expect a little pecking order stuff, but I doubt it would last. It is not impossible that an adult of any of these triggers could see a smaller fish as lunch.Just a thought: sell the BC and get a pair of CHs. They really behave like a true pair and are magnificent fish. Personally, now don't get mad, I just think BCs are boring and reclusive---especially for triggers.
 
Thank you for the first hand knowledge, I appreciate it. If there would be any fighting it would be the blue throat that goes.
 
I read an article (on either Advanced Aquarist or Reefkeeping) that said they live in sargassum mats as only juveniles.

I believe that's correct. But they still can be found far from any reef, feeding on critters that are also within the protection of the floating mass. The walls of reef drop-offs are also good feeding spots for them. BTW, I think most sources consider these triggers to be carnivores.
