Thank ye, Chris. I would've guessed that there would be some conserved
phylogenetic similarities within the genus (and I don't have the Goldstein
tome). I've always heard that chrysocephalus was associated with
nestbuilding aggregations of other minnows, so I figured that was the most
obvious answer. But I've never seen any descriptions of aquarium breeding,
which seems strange given how common the fish is.
