How many gallons is that? Around 45? If you're looking for something other than a community tank and want something impressive, try african cichlids - research malawians if you want lots of color. I suggest you begin with yellow labs and look for cichlids that are compatible with them. Some good species to consider seem to be pseudotropheus acei, iodotropheus sprengerae, pseudotropheus socolofi and pseudotropheus saulosi. Also consider a bristlenose plec and/or some medium-sized synodontis catfish species to go with them.
If you want, you could also go for a discus tank or angels and of course there are tiger barbs if you want a frenzied species tank... Well there are many, many species that would do best in a species tank. Maybe look into some kind of oddball?
Or maybe get a single CAE and see how big you can get it to grow
What exactly would you like? What are you after? Do you have anything in mind?
As for what I would do... pearl gourami grow-out tank

(and then I'd go for a tank filled with FFs, FSAEs, SAEs and otos - just to confuse people).
