We have peninsula crayfish (Procambarus paeninsulanus) $2 each, plus shipping (for 10-20). I can cut that price in half for bulk orders (50+). These crayfish are from the swamps of central Florida, are usually 2-3+ inches long and have two main color phases, a swamp green and a copper color. Crayfish can thrive in aquariums or ponds if they have access to the water surface via plants, logs, rocks, or other structure rising from the water’s surface.
