Likewise, they hunt small invertebrates and may occasionally eat live crayfish and frogs. ![]() In their native environment, they would eat leaves, rotting wood, roots, and moss. What to Feed CrayfishĬrayfish are omnivorous creatures and enjoy both meat and plant food types. A young crayfish will happily accept commercial feed, frozen meaty items, and blanched vegetables. It would be best if you housed the young crayfish in a smaller aquarium because they can be a tempting food source for other aquarium species. In a community aquarium, it is better to separate the female before the eggs hatch. In the next three weeks, the female would rarely leave her hideout. The eggs would look like berries found on the female’s underside, where they are well-oxygenated by the swimmerets’ constant movements. Mating finishes about 15 minutes, and the female will start laying eggs within a few hours afterward. The male will push its sperm tube through one of its pleopods and deposit its sperm into the female’s annulus ventralis, a pocket to hold the sperm. Mating starts with the male grabbing the female and flipping her onto her side or back. If you have a pair, the two will do their own thing. Crayfish BreedingĬrayfish are easy to breed as long as you keep the water warm and clean to ensure breeding behavior. However, the crayfish lifespan tends to be shorter in the wild. You need to make sure your crawdad can hide from intruders until its shell is hard enough to protect itself.ĭepending on the species, crayfish can live 3 to 5 years while in captivity. An important thing to note, though, is that the new shell is soft and pliable, which makes it easy prey. Molting is normal, and you can expect it to happen a couple more times in the future. However, some crayfish might not be able to free themselves entirely out of their shells, and they eventually die. Do They Die After Molting? Lifespan & Causes of Death As for the calcium-rich exoskeleton, you will want to leave it in the tank for your crawdad to eat. Fully grown adults will molt only to generate lost limbs. The frequency decreases over the years as it matures.
