Why did my crayfish die after molting?
Adult size is reached by crayfish in the wild in about 4 years. They can live from 20 to 30 years. During the breeding season, males fight for the right to copulate and, in these competitions, they may lose a leg or claw. This is no problem, as they will slowly grow back.
Early Signs: The early signs of moulting include lack of appetite and a slowdown in activity. During this period the crayfish ingests calcium into an internal organ, not into the exoskeleton. Hiding: When the crayfish is ready to moult, it will try to find a hiding spot.
Crayfishes mainly die due to poor water parameters. They can also die because of larger & aggressive tank mates, uncycled tank, lack of oxygen and of course, too much age.
Tip: Do not remove the old shell, crayfish will consume their entire exoskeleton to recycle necessary minerals and salts to aid in the calcification process. That is why it is also advisable not to feed crayfish for a few days after the molt.
The amount of time it takes a crayfish to molt is also determined by its size. The smaller the crayfish the less time it takes to molt. In most cases, it usually lasts from 24 hours (for small and your crayfish) to 3 – 5 days for adults and big ones.
Crayfishes are generally very hardy creatures. So, if your crayfish has died, there is something wrong with your crayfish tank setup. Crayfishes mainly die due to poor water parameters. They can also die because of larger & aggressive tank mates, uncycled tank, lack of oxygen and of course, too much age.
Crayfishes stop moving or move very little during the molting process. They can also stop moving due to excessive stress, wrong water parameters, or unsuitable tank mates. Though crayfishes generally stop moving during the molting process, many other reasons can be responsible for this type of behavior.
The molting of crayfish is normal. Because when crayfish molt, they are more soft and vulnerable. Also, and this is very important, never remove the molted exoskeleton from the tank when your crayfish has molted. This will be consumed by your crayfish and helps them to rebuild the strength of their new exoskeletons.
Molting. Molting is usually accomplished in minutes. The brittle exoskeleton splits between the carapace (head) and abdomen (tail) on the back side, and the crawfish usually withdraws by tail flipping. During the “soft” phase that follows, the soft exoskeleton expands to its new, larger dimensions.
diminutus will die part-way through the molting process. It appears as if the claws and all of the legs do not make it out of the old shell and get ripped off of the body. The crayfish does make it out of the front half of its old exoskeletonbut not out of the part covering the abdomen.
