Finally I found some! I got six today. They must be juveniles- they are so tiny. Maybe 3/8" long, and no black stripes on their fins yet. They went in a ten gallon that has nine pygmy cories (hastatus) and seven threadfin rainbows, plus a gold tetra I can't catch and a male honey gourami (the real one, tiny, not a colisa hybrid). All of a sudden, the gourami looks like a grouper! The only fish I am worried about hurting them is the tetra, but so far they seem quite alert and adept at avoiding any fish that come near. I will try for pictures when they settle down...
