The female will hold the eggs between their anal fins for a while, but they end up depositing them on something to hatch. It’s a pretty interesting site. I keep them in a tank with a floating spawning mop and periodically pull the mop. I don’t put much other decorations in the tank so they will really only deposit on the mop. I find if I leave the eggs with the parents for too long, most of them will get eaten. They can actually handle cold temperatures really well. I have had them in tubs outside for a while now. I haven’t really done anything special that I’m aware of to induce spawning. They get a normal round of small flakes, really small (0.5mm) pellets and the periodic frozen cyclops or leftover baby brine shrimp.
