When choosing a Striped Synodontis, attention should be paid to the fish's activity and the condition of its skin. A healthy specimen should have a clear, contrasting pattern without whitish growths, ulcers, or fin damage. Avoid specimens with sunken bellies or signs of emaciation, as this may indicate internal parasites or problems with adapting to food. — Check the integrity of all fins and the absence of redness at their base. — Ensure that the fish shows natural caution but does not appear overly timid or apathetic. — Observe their behavior in the store: healthy catfish often stay in hiding, but when feeding, they should show interest in food.
