The recommended aquarium for keeping walrus fish is 4.5 meters long, 1.5 meters wide and 1.5 meters high. Therefore, walrus fish can only be kept in large aquariums. When placing walrus fish in a fish tank, it is necessary to ensure that there is enough breeding space and a wide range of activities for the fish.

If the water level in the tank is low, protective measures must be taken on the top of the tank to prevent it from jumping out and causing unnecessary losses.

Extended information:

Arapaima lives in the most primitive tropical jungle waters in the world. It mainly feeds on small fish, but occasionally preys on snakes, turtles, frogs and Insects and even small crocodiles will be preyed upon.

Due to the extremely hot weather, the oxygen content of the slow-flowing river water is reduced, and the arapaima needs to rise to the surface from time to time to swallow air to breathe. In the dry season, it can also protect itself by drilling holes in the sand.

The arapaima has strong brute force. Using its tail as a weapon, it can easily knock down an adult male and break its bones to cause massive internal injuries.

Arapaima spawns in the shallows like salmon. January to May is the spawning period, and about 160,000 eggs are laid in multiples. The eggs hatch in about 5 days. At this time, the tail of the male fish turns red. It is the male fish's responsibility to protect the eggs and take care of the newly hatched juveniles.
