When observing a healthy Zebra Pleco from above, what specific feature regarding the body structure indicates proper development behind the pectoral fins?

Answer

The area just behind the pectoral fins should be as wide as, or wider than, the head

The body structure of the Zebra Pleco reflects its Loricariid heritage, featuring armored plating and a flattened underside suited for life near the substrate in flowing water. To assess if a specimen has achieved optimal growth and was not stunted during its juvenile stages, observing the girth behind the pectoral fins is essential. A robust, healthy adult will display a physique where the main body section immediately following the pectoral fins matches the width of the head, or is even slightly broader. If this area remains significantly narrower than the head, it signifies underdeveloped growth, often stemming from suboptimal environmental or nutritional conditions experienced early in life.
