Well, took the lone tetra (fry that arrived as egg on plants to adulthood) to the pet store to give to guy who has large planted tank and schools of diff tetras. He shows me a tank of Australian Rainbow (Tetras) that look exactly like my guy/gal. (started showing blue flashes in scalses otherwise pretty non-descript)

Get home and do some research and seems not a tetra but variation of rainbow fish. The one that comes closest is female version of the one at this link... I hope it gets along with tetras! It was sometimes agressive by it's self, but also swam with others in tank (betta while in it and three cories) mostly agressive around feeding time.. I hope they get along. I miss it already but thought it would have a better home... we shall see. Best Sherry
