If I were to do it I would have most the plants a dark shade of red. Like glandulosa and less of them a bright orange red. Mixing in some gold nesaea would be cool, but that may mess up your red Star Trek theme. Though the aliens in the movie are yellow! Awhile back I had glandulosa next to nesaea gold and it was one of the best contrasting colors I have ever used. For sure get blue fish. The fish should not have any red. White,blue and yellow fish would be best. Good luck. Hope to see it soon!
