Please identify the fish described (no photo) (Columbia, MD)

I was in the Hunan Manor the other day, in Columbia, Md, on Broken Land Parkway, near the 3 Brothers Italian Restaurant. Ok, these Asians have a nicely set up, and humungous aquarium, which contains a variety of interesting looking fish. This one fish is new in the aquarium, at least within the past 3 weeks. Description:
It's about 3 inches long, maybe 4 inches.
It is able to flare out it's fins, to make a display like a male peacock. (only, this fish's color is mainly silvery-orange. Really no other colors, mainly the orange-ish color all over) It has fins on the side and top, and I think one on the bottom. Can you identify that fish? I failed to ask anyone.
