I've had a small group of 6 (4 males, 2 females) for several months, and while the females are about an inch, and looking very nicely colored, I haven't seen any fry. It looks like both females are gravid, one very much so, but no sign of babies. The only other critters in the tank are shrimp and snails. Thoughts?
They do breed continuously from what I've seen and when I worked for a pet store that kept them in the back room for creating continual fry factory's, they did do just that. You must have them in quarters that will accommodate the "everyday" 2-3 young idea. If you have enough bushy type plants you'll find that some do survive over time.
Oh I know that they only have a few young per day. It's just that after 2-3 months of them being clearly pregnant, I thought I'd see something by now. The tank is pretty well planted with crypts, moss, anubias and dwarf water lettuce, so I guess there could just be enough hiding spots I'm not seeing anything
