YES! As in, a DEFINITE NO on the paradise fish. And please, Fishman, don't destroy my faith that you are turning the corner about listening to advice here about what your tanks need - just pick what was said here is a good pick, that you also like, put ONLY them in the tank after it is properly cycled and all the stuff you know about, right? And then for blessed's sake, sit and watch your fish being HAPPY.
Then post pics for us every day! Tell us how funny your one mbuna was with the other, or the way your one gourami loves its 10g.
I understand that you are trying to do everything according to the advice you've had here. That rocks! But just take the previous stocking lists, add to tanks slowly, and enjoy. Stop messing with new combos. It's driving YOU crazy, it seems.
Plus, when you are able to own and maintain as many tanks as you want, well then you can have everything you were ever curious about. For now, m'dear, set up a couple of healthy tanks. We'd love to see that.
