this species wasnt introduced into the hobby until the early 60's.
however, since their introduction, there have been only a handful of documented captive breeding experiences(literally, one hand full). there are theories as far as how to do it, but there is very little known about the actual breeding activities, and its really hit or miss. most exodon keepers will never experience breeding activity.
my statement is sourced from
http://www.angelfire.com/biz/piranha038/exodon.html. and that particular article is written by a man who's spent most of his life acquiring information about South American species and the like. you sure you dont mean when it was introduced to hawaii? he never mentioned the status of the woman who bred the fish in home aquarium conditions..
but you, quit sapping every post i make about exodons...
"BREEDING
The fish has been bred in captivity at 2 1/2 inches. Females are broader and heavier than the male. Males have a slightly longer anal and dorsal fin rays than the females. The dorsal, anal, and pelvic fins are reddish, adipose yellow, caudal yellowish basally, lobes pink; back brownish, silvery ventrally, tinted yellowish. The female is generally yellowish.
The species was first bred in captivity in 1955 by a 17 year old named Martha Tutwiler.
According to Tutwiler, breeding this species is difficult, because of the fast swimming nature of the species. They were fed live foods and were constantly eating. The species are fin-nippers and recommended no other species be kept with them. The spawning took place in a ten gallon aquarium densely filled with artificial spawning grass (Spanish moss). There were only two inches of clear water above the plants. The breeders swam back and forth releasing eggs and eating them as they fell. Miss Tutwiler, assumed that if they had been provided a larger aquarium she would have been able to save more of the eggs. The fry hatched from the eggs in about 48 hours at 74°F. Breeders must be removed after spawning."
