I personally would leave out the Oscar. Are you against ordering fish online, or having some shipped to you from another hobbiest? If your willing to have fish shipped, then the world is your encyclopedia. There are so many cool. colorful, beautiful fish out there. Sorry if I step on toes, but there are far more attractive fish available than Dempseys, FM, GT, Oscars.
I myself will be ready to start selling some little ones. I have F1 Devils, F1 Hogaboomorums, Red Isletas, Festae, Jags, Dempsey x ELBD, Zonatus, F2 Carpintis Escondido, Xiloaensis (dad is white mom is barred). Soon to spawn are Dovi, Umbee, Xingu/Org Pike.
This is just my few of many of mine. Many people have fish available. You should really look into buying online. Like Gage from Cichlid Connection has treated me awesome, and his fish are superb. Jeff Rapps also has sent me some beautiful fish.
So to answer your ?. If your content on the choices you provided. I would get a couple GT, a couple FM, and a clown loach or 2, maybe a polypturis. But I like to stock my tanks a little on the heavy side.
Let us know what you decide to do.
