When choosing Peckoltia, attention should be paid to the fish's activity and the condition of its skin. Healthy individuals should be mobile, without visible damage, ulcers, white plaque, or signs of emaciation, where the abdomen appears sunken. It is important to consider that these are nocturnal fish, so in the store they may be inactive and hide in shelters, which is normal behavior. — Avoid buying fish that show signs of timidity or apathy, if they lie motionless on the bottom or near the water surface. — Check the cleanliness of the fins and the absence of signs of rot or damage on them. — Ask the seller what the specific individual eats, as adaptation to dry foods in captivity can vary individually.
