Thanks guys. They're actually a little smaller than the 2 platy fry they're in with at the moment, but it'll be interesting to see what happens as they begin outgrowing the platies. I think they'll end up being good buddies.
Pat,
I have another thread in this section of the forum entitled "Happy Krib Pair," which should provide you with the answers you seek. Like Stradius said, they are very easy to breed.
The real trick is in finding an actual pair...
Sometimes they don't like each other, and one will kill the other.
Once they're a pair, the rest takes care of itself. The female will typically lay eggs on the side/roof of a half-coconut shell or similar cave-type dwelling. Parents take turns guarding the eggs and keep guarding their brood when the fry are free-swimming.
Mine guarded their fry for about 2 weeks, at which time I separated the fry from the adults and put them into their own tank (for all I know the adults would have kept protecting them a lot longer
).
