How to Keep Crayfish? A Detailed Guide to Breeding Methods and Key Technical Points
Crayfish are aggressive ornamental shrimp, and many beginners do not understand their habits, so they often fail to keep them well.How do you keep crayfish? Read on to find out.
1. Fish tank
When keeping crayfish, you must ensure they have enough space to move around. Make the aquascape in the tank as complex as possible and set up more hiding places. Crayfish are also called destroyers, which shows that they are absolute strongmen. Do not keep too many in one tank, otherwise it will cause casualties.
2. Substrate sand
Native crayfish live on sand and gravel. To provide a better living environment for crayfish, you can choose the substrate sand according to the crayfish species. A crayfish's own color will change with the substrate sand, so when choosing substrate sand, pick it according to its own color. For example, if black corundum sand is used for the sky blue devil crayfish, the body color is generally better than with the equally neutral Dutch sand. The substrate sand for keeping crayfish needs to be mixed with some materials that can release trace substances, so that crayfish can replenish energy in time when molting.
3. Filtration
When keeping crayfish, the filtration must be powerful. Crayfish eat and produce waste very heavily, and powerful filtration can keep the water quality stable. Crayfish have relatively strict requirements for water temperature. The water temperature can be kept at around 22 degrees, and the temperature must not be too high. Of course, if breeding, it needs to be raised appropriately.
4. Light and oxygen
All crustaceans need to molt in order to grow gradually. After molting, they need calcium supplementation, which requires the cooperation of light to help crayfish restore their majestic appearance. Oxygen is also essential. When crayfish molt, it is the most vulnerable time, so sufficient oxygen must be provided.
As long as you pay a little attention during the keeping process, crayfish can be kept very well. I hope this can help those of you who like keeping crayfish.
