Just remember, small (young) readily need a food source, such as algae and the bio-film from an established tank. I would not recommend cycling with them at all. It is not uncommon to see the following in their bios.." Aquarium specimens may starve for lack of algae or other plant matter; algae wafers or other low-protein foods are recommended. Keepers should watch for the abdomen to take on a sunken appearance, indicating insufficient nutrition."
