I feed mine stapled food that goes right to the bottom.
I'm wondering though, if I wanted to move some in a new tank, would I need to cycle a tank? It will just be 1 or 2 gallons without a heater or a filter. Would I just be able to put one in, where they breathe air? I heard too that they don't need real live plants, so I keep mine with fake and theyare doing good but I'm just curious if you can just put them in a new tank after letting it sit a few days. Sry not to hijack the thread!
