(If you feel Experienced)Does this sound like a good choice of fish for my aquarium?(please answer :D)?

Be careful paring gouramis. You'll want one male and one female if you choose to have two. I've had two males in a 29 gallon aquarium before, and it's not TERRIBLE. However, they will spar often and if they do not have adequate space to claim, they will not be happy fish. Also, on the low sided estimate, you're looking at 14 fish in a 30 gallon. (I realize some of them are smaller breeds...) Be careful with over-crowding. Fish can become agitated if they don't have enough room, leaving them open to disease, not too mention it will require alot more maintenance to keep clean.
