That should be possible. I have been raising baby crabs for several years. 1. It is best to use a fish tank with a lid to prevent crabs from escaping. Plant an aquatic plant and put some pebbles and sand to more realistically simulate the crab's wild living environment. Crabs are also burrowing animals. It is best to pick up a tile, clean it and put it in the fish tank so that it can live in it. Crabs also need to bask in the sun, but not for too long. 2. Feed the crabs food such as bread crumbs, potato crumbs, steamed bun crumbs, rice, snails, small fish and shrimps. 3. Change the water once a week. It is best to use natural river water or lake water. If not, use tap water that has been exposed to the sun for two days. The water should cover the back. 4. When crabs shed their shells, their shells will turn yellow and their bodies will become soft after shelling. They should be kept separately from other crabs to avoid cannibalism. And feed more meat foods, such as small fish and shrimps. If successful, they can bring you a lot of fun. Hope this helps, friend.
