Reproduction

Crayfish in aquariums make fascinating pets. Individual reproduction won’t lead to issues if the right circumstances are established. Because every resident is unisexual, sometimes this process cannot be completed.

There are significant differences between species in terms of individual size and maintenance requirements. Crustaceans essentially reach sexual maturity at three months of age. The vivid red stripes on the claws are another way to identify males who are ready for reproduction. Since he can eat the female after fertilization, there should be at least two females for every male.

Usually, the breeding season starts after molting. Enzymes secreted by the female draw in males. The mating ritual, which can take several hours, involves the species touching one another with their antennae. The female should be moved to a new container once it is finished.

The creature lays eggs 20–25 days later. During her pregnancy, the female is inactive and favors being in a shelter. The babies are carried on the person’s abdomen until they molt after birth. The babies are defenseless at first. Shelters should be included in the aquarium so that the babies can hide from each other and avoid becoming food during the shell-shedding process.

The female crayfish is removed following their second molt, marking their increasing independence. It requires frequent water changes as it gets bigger. After a few months, the young are moved through the tanks because they grow too close together in one container.

So that troubles do not arise, it is better for them to live in different aquariums.

Crustaceans can occasionally be destroyed by big fish. This happens when the arthropod’s body is molting and has lost its protective covering.

With other inhabitants

The fungus Aphanomices astaci is the cause of the illness. When it manifests acutely, the arthropod’s nervous system is paralyzed. The virus has no known treatment.

Untreated soil contains fungus spores that crayfish bring into the aquarium. Both the heart and blood vessels are impacted. Brown patches on the gills are indicative of the disease. The crayfish first gets lethargic and eventually perishes.
