The paradise gouramis are a bad idea, methinks.
They're a very aggressive species, and may outcompete the Red Turqs entirely for food. More importantly, they'll cause undue stress in the tank. The Paradise Gouramis I've seen at the
LFS, and that I've read about, are a really ornery, territorial bunch. They have no qualms about nipping other fish, big or small.
Sorry to be the stern voice of doubt...
I don't think, Ishmael, that anybody on this thread has really stressed to you just how time-consuming and picky discus are. How much experience do you have with fish? If you are a relative newcomer, I'd *really really really* suggest that you think about another relatively picky species first. Build up to the Discus. I've been keeping fish for a while now, but don't think that I can commit to the schedule and work load that discus would require. There are just so many potential problems... And are you prepared for daily water changes, esp. if you have to go away for a week?
In addition to this, I think you may not understand how sensitive a fish discus are in relation to having other tank members. There really are only a very few fish that can be kept with discus because of their water, social and feeding requirements.
Think long and hard before getting yourself into a situation you might later regret, please. :? I know this isn't what you want to hear.
