When selecting individuals in a store, pay attention to body transparency: in healthy fish, it should be clear, without cloudy spots, film, or hemorrhages. Avoid specimens with damaged fins or signs of emaciation, where skeletal bones are prominent. Since this species is schooling, acquire a group of 4–5 fish at once, as solitary keeping causes them severe stress. In the store, observe their behavior: healthy catfishes stay in the water column, show activity, and react to movement from outside. Lethargic fish that constantly lie on the bottom or try to hide in the corner of the aquarium may be weakened or sick. Make sure there are no aggressive species in the aquarium with them that could cause injuries, as injured fish adapt extremely poorly to new conditions.
