Anti-swimming cats (definite introduction)
The anti-migratory catfish belongs to the genus Synodontis of the family Synodontidae. Due to their different origins, their species, body color, body shape, and size vary greatly.

River-type anti-migratory catfish are mainly distributed in Lake Nigeria, Lake Niger and Say River system in West Africa. Rare varieties include the gypsophila cat and the black-winged cat. This type of species has extremely strong adaptability, has less requirements on water quality, and can survive, grow and grow well in weakly alkaline to weakly acidic waters.
Lacustrine anti-migratory catfish are mainly distributed in Lake Tangoike, Lake Malawi and Lake Victoria in West Africa. Rare breeds include spotted cats and Victoria cats. This type of variety has higher requirements for the water environment, requiring the water to be alkaline and relatively hard, otherwise it will be difficult to survive.

Migratory catfish are susceptible to white spot disease, and water quality control should usually be strengthened to prevent gradual changes or reversals in water quality. The reason why it is named anti-swimming catfish is probably because it is different from other fishes and does the opposite. It is good at backstroke, swims fast and has a weird appearance, so it has always been loved by aquarium enthusiasts.
