In addition to aquarium fish, freshwater Yabby lobster is currently the choice of many people who love exotic pet breeds. Yabby lobsters are most popular due to their distinctive color. This is an artificially bred shrimp belonging to the land lobster family. Today’s article, WewPet will help you learn a lot more interesting things when breeding this ornamental shrimp.
Features of the Yabby lobster
Yabby Lobster (English name Cherax destructor) is derived from the same common freshwater lobster. Through many generations of close hybrids, they have a distinctive blue color like today.
They have a relatively long lifespan compared to other crayfish species. From 3 to 6 years. However, it is also reported that some individuals live up to 8 years. These Yabby lobsters are very ferocious and territorial with their species.
The molting process
Yabby shrimp molt to grow, when born, about 3-5 days they molt once. The bigger the shell change time, the longer it will be. The time of molting shrimp depending on the condition of each animal will be long and short. The difference is about 1-2 minutes.
One sign that Yabby freshwater aquarium shrimp is about to molt is that they will not eat. Often lying in one place, less active, the legs and the more red changes. The coupling between head and neck is visible.
In addition, if the shrimp are injured, they will quickly grow back in the injured area. The relatively unsightly shape, however, affects the growth of the shrimp in the long run.
After removing the old shell, the Cherax destroyer will need a place to hide until the new crust hardens. Remember that freshly molted crayfish is exhausted, stressed and susceptible to predation due to a lack of protective shells.
After molting, the metabolic demand (to harden the shell) for Calcium is particularly large. Landscape lobsters use calcium to create a new, healthy shell. So, please pay attention to calcium supplementation for them to the fullest.
Yabby lobster habitat
Shrimp farming is at 20 – 30 ° C, ideally 24 – 26 ° C. Too low temperature will affect the high speed of shrimp, high temperature hinder the peeling process. Shrimp that cannot peel will quickly weaken and die.
Yabby shrimp can live in water with a pH of 6.5 – 9. However, it should be raised in mild alkaline environment, beneficial for molting to grow. The water is too acidic to make the skin softer, which is especially dangerous for them. So pH controlled at 7.2 – 8 is the best.
Solution: Use black background gravel, coral sand and maifan. Black-based gravel helps increase alkalinity in water, coral sand maintains hardness, maifan is able to absorb impurities, helping to purify water.
It is usually buried 0.5-2 m deep in mud or holes and can survive for several months in caves. They are active mainly at dawn and right after sunset.
Yabby lobster food
Main types of food
In order for Yabby lobsters to be healthy, their food plays an important role. Regularly feeding shrimp commercial feed will reduce their lifespan. The reason is that industrial feed has very low levels of Anbumin, which is not enough for shrimp to grow well.
The worms and the mackerel are the two most popular live bait types today. In addition, it is possible to feed them raw or dried shrimp, which is also a good source of nutrients but relatively high prices. Young shrimp can be fed with earthworms, larger ones can combine worms and seabass.
Boiled lettuce, cabbage, zucchini, carrots … are a popular choice to feed Yabby lobster. Fish or shrimp algae … are fine. They are not fussy eaters. They will eat whatever you give them.
Artemia should not be fed to Yabby shrimp, as this species is easy to carry toxins from the outside environment. Freshwater aquarium shrimps are omnivores that eat plants.
Note when feeding
Be careful not to overfeed. They have a small stomach and will stop eating when full and leave the rest of the food behind. It is also not necessary to feed them every day.
You can adjust your habit of giving them two small pieces of food every 2-3 days. For a healthy living environment for them, try to remove any leftovers in 2 hours.
In the wild, this shrimp has the ability to convert food flexibly. For example, when protein-rich foods such as fish, snails … are restricted, it can easily switch to a diet mainly plant, harmful algae.
Yabby freshwater aquarium
In addition to water quality and temperature, aeration is required for 24/24 shrimp culture tanks. Undernutrition tank is one of the reasons why shrimp cannot peel and die. Yabby Lobster doesn’t need too much water. Because a lot of water puts great pressure on them, making it harder for them to drain.
A tank with many shrimp should pay attention to put driftwood and rock to create a shelter for them. Because this species of shrimp has very strong territorial behavior. Furthermore, when shrimp is about to peel, it is necessary to isolate them from other individuals. Avoid a mutual attack. It’s best to give the Yabby Lobster plenty of places to hide from cooking.
Water filtration and aeration are two indispensable devices when farming Yabby lobster. Also need to change water periodically, once a week is appropriate. Each change only needs to change 1/3 of the water, not to drain all the water in the tank.
The current price of Yabby freshwater ornamental shrimp in Vietnam is quite high due to the low supply and the need for a lot of experience in farming techniques. However, they are still the number one choice for many hobbyist enthusiasts today.
