They're African Annualfish (kind of Killifish/Pupfish) that live in temporary pools in the desert. They live one year (because the ponds only last a year) but they lay eggs as the ponds dry, which hatch when the pools fill back up. I remember reading somewhere that if they are kept longer than a year (past their lifespan) they start to get dilapidated and waste away :eek: They would probably do better in a tank than a bowl, but then again, in the wild, they live in ponds that reach temperatures in the high 90's, and re stagnant, so they're pretty much impossible to kill.
 
Breeding directions from liveaquaria:

This species of Killifish is an annual species. A breeding tank is ideal with a 2-3 inch layer of peat at the bottom. The Korthausae Killifish will bury the eggs in the peat. After spawning, remove the peat that contain the eggs and press out any excess water. Place the moist peat with the eggs in a plastic bag or sealed jar for 3 to 4 months at room temperature. After that time period, add aquarium water back to the peat to hatch the fry.
