sold me a pair of "Red Spotted MicroRasbora" and all they had was the one pair. I really like them and would love to find more--but the name seems to be a dead end as there is no red on them and they are about an inch and a half long. They have a broken lateral line which may be considered spots I suppose.
These two are in my 46g with other very small active fish, including Threadfins, Pygmy Cories, Cardinals, etc. in fact the largest fish is my three oldest Oto's. The reason I like them is because they are nearly always near each other. Sorry about the lousy photos, but they are always in motion!
