I've had success with panda cories. I have the adults in my community tank, so when they lay eggs (mine always lay on the plants) I pick the eggs off, put them in a net bag hanging in the fry tank, then when the eggs hatch the wigglers are released into the fry tank. By hanging the eggs in the fry tank, I can still vacuum the tank without burying the eggs, but they get the benefit of water circulation and the same water conditions they will have after they hatch.
I feed the fry frozen baby brine shrimp, live microworms, and finely crushed flake food. The tank (2.5 gal) has a sand substrate which I "fluff" and vacuum daily, with a turkey baster, which accomplishes a 50% daily water change. Excellent water conditions are key. The water is just tap with Prime. The tank has a couple small Java ferns and a piece of driftwood for the babies to hide on/under.
As far as getting the adults to spawn- who can stop them??!! Mine mate and lay eggs at least once a week. I don't rescue all the eggs, only when the fry tank is getting low, so most of them get eaten by the tetras in the community tank. I feed the adults flakes, with algae wafers and frozen bloodworms once a week or so. Like many others, I've noticed that a largish water change with water a few degrees cooler is a spawning trigger. My biggest spawn to date (>40 eggs; pandas aren't very prolific) was when I did a water change the evening before a huge storm, when the barometric pressure was dropping.
Have fun with your cories- the babies are so cute!
