I hope they do! I have 10, so the odds are good that I have at least one of each gender eh? The males tend the eggs in small caves, and those that have bred them use small PVC pipes. Hard to tell from my pic, but they are about 1" long, and full grown. Gonna hafta be small pipes!
They are really shy so far, and the tank they are in is HEAVILY planted and full of algae (on purpose - indirect sunlight and 14 hours of light per day). I've used this tank to make 'algae logs and algae rocks' for my otos, and its perfect for these fish to snack on the infusoria in there. They don't take to commercial foods normally, so I'm going to offer some microworms tonight.
10 in a 10gallon tank and couldn't SEE one of them this morning! I want to get a few more pics if they come out of hiding, that show their color. That pic I posted was just seconds after being released from the shipping bags and after being drip acclimated for an hour.
