Leech Bed that keeps your moss half-wet and half-dry. Primarily this bed can be attached to the walls of your leech aquarium or container and laden with leech moss. The pregnant leeches can easily crawl in and out of the moss through the holes and can lay their eggs on dry top portion of it, while the bottom half stays moist and submerged under the water for the leeches to hang out in and hydrate themselves.
