I originally got this tank intending to use it as a seahorse tank. However, life got in the way and it was converted to a freshwater tank. It's been in limbo for over 10 months, with only a few fish to cycle it. In December it got a bit of an overhaul, when I added an Aquaclear 70 filter and some Java Moss, in addition to three Pygmy cories, two dwarf pencilfish, and a betta that have been in there since November.
Today I added a Corkscrew Val, another pygmy cory, and an albino bristlenose. They seem to be doing well. Currently I have two T5 bulbs over the tank.
Plans:
Add more plants
Get another 7 pygmy cories

I'm considering a school of threadfin rainbows, I've had them before and I enjoy their mating shows. What are some other schooling fish that are super peaceful and small? I would also like some sort of centerpiece fish. I'm leaning towards gouramis, whether Sparkling, Croaking or Pearls. Any advice? I would like the tank to be very peaceful and I might add shrimp in the future.

Go with the smallest of the little Gouramis.
Threadfins are nice schooling fish. There will be some activity with the males showing off, but no real aggression.

I do love the Sparklers- mine had great personalities! Do you think that there's room for a school of all three species, or just stick with two? I'm not sure I could find the Dwarf Cats locally, but I could always get them shipped.
