As for adding color, how about a pair of Peacock Gudgeon?
I have RCS, CRS, Bamboo, Ghost, and even Opae ula shrimps. With good water conditions, they seem to be doing just fine.
As for compatibility,
as for tank mates, a real good cleaning crew and just Discus... USPost Office has lost another box of Discus, 8 Reds out of Florida. Were to be delivered
That looks good, thanks!
