were quite good spawners, but one by one I lost a few, until for the last 2 years I've had only 2 males. Well that's over now. In June I picked up a mixed sex group of 8 smallish (I infer young) adults from Anthony Mazeroll at the Amazon Research Center for Ornamental Fishes.
I put them through QT in a 10 gal tank then later added the two big old males. Today I was blessed with one of the biggest spawns I've ever seen from such little fish.
