Crayfish can be an exciting addition when you set up a fish tank at home. They are an excellent choice for the people who want to keep pets but don’t want to spend too much time taking care of them. Looking at them when they move here and there in search of food and exploring their surroundings is a pleasure. They usually interact with their owners, which makes them enjoyable to keep as a pet. Crayfish are not safe for a community fish tank, but many people successfully keep crayfish and other fish together.
You only need to do some research on finding their attributes, behavioral changes, and best tank mates so that whatever species you choose to keep with other fishes to be safe. It is awful to lose a large, costly fish to a crayfish over the night. Their aggressiveness can change under certain conditions. For example, some species, such as the Australian crayfish (Cherax Dispar), are extraordinarily aggressive when they molt or before it. In some species, increased or decreased water temperature can be the cause of aggressiveness. Some species are more aggressive and try to hunt tank mates when hungry.
There are approximately 600 species of crayfish present on Earth. Half of them occur in North America. Due to this diversity, they are present in almost all types of aquatic habitats, including freshwater and brackish water. Some species live in brooks and streams where there is freshwater running. Some others can be found in ditches, swamps, paddy fields and sloughs. These aquatic invertebrates can be a challenge sometimes, but their unique attributes and beautiful colors make it all worth it. We can easily keep them as pets in a home aquarium. If we understand its different nature and respond to certain stimuli, we can manage an environment where they can live with their fellows comfortably.
