What choice fish to breed in 55 gallon

[KINGMED]

Setting up 55 gallon in a few days, have been planning on doing this the last 3-4 weeks but just got my pool filter sand last Monday. I would like to breed a fish that eventually I could sell in the area that is not common. Shell dwellers can not be found in the area and I might be able to sell some, don't know? Want a fish that looks nice that others would enjoy watching, Multi's are nice to look at but not real pretty, have even thought about some endlers and I'm sure I could get tons in a 55 gallon, don't find them around here either. My concern is I want a fish that will look nice, raise their young and be a good fish to sell in the area.

Blue Acaras get my vote :22: aswell as Apistogrammas

If you want attractive shellies then consider Ocellatus Gold. Very striking, if a little mean! V interesting to watch and breed easily in the right conditions.

Cutteri are pretty awesome fish, breed prolifically, aren't easily found, and take great care of their young.
