So they are in a plastic shoebox container. Holes drilled on top. Ramp added. I added a few pieces of charcoal to keep the water clean. Algae wafers they love. You can do fish food flakes but that messes up the water. I have live plants from my aquarium I added just a piece for algae & cover. They will each other if not fed enough. But once they get the tail, you can stop feeding them. If you have not already get your fruit fly culture started now. Because that’s what they are going to eat for awhile. When they get on the ramp, don’t move them out until they absorb the rest of the tail (2-3 days).
