I had a group of them in my 10 gallon QT tank for a few weeks, and they spawned several times. The fry seemed to be doing fine feeding on whatever micro-critters they found among the java moss and floating plants, then would disappear overnight. I took down the tank thinking to replace it with a 29, then found there wasn't enough space above it to do water changes. I put the 10 back in place, but left the 5 gallon bucket full of water sitting on the floor ratehr than immdeiately dumping it. A couple days later I saw some fry, after a week I counted 7. They remained in the bucket with a dozen or so ramshorn snails and some debris from the siphoning of the tank when it was emptied until a few days ago. No filter, heater, or even water changes for probably 2 months, just duckweed (replaced a couple times after the snails ate it) and once daily feedings of powdered flake food. They all grew out just fine, while I only had 2 of the fry in the 10 gallon tank survive long enough to grow out to a similar size.
I use 2 flat pieces of marble to grind flakes into a fine powder for tiny fry.
