I just got these little ones the 12th, Currently they are eating Frozen Brine Shrimp and Frozen bloodworms. They will be moved into my tank as soon as they are big enough, For now they are in a 1 gallon holding tank.
My 5 gallon has hides and Marimo and Two Anubias Nana but its sand substrate, its SUPER fine though .5-.75 mm according to the site, running my fingers through it I can not even feel grains. They have a heater in their holding tank thats 25 watts so when they are ready to be moved it will be moved with them. I am keeping them an 75 degrees and feeding them daily. Water changes as needed , At least 1 100% change weekly.
