Archerfish shoot jets of water to knock insects from overhanging vegetation. Their remarkable hunting behaviour reflects sophisticated neural processing that makes their welfare in captivity particularly significant.
Archerfish welfare in captivity requires environmental conditions that allow their signature hunting behaviour — without overhanging prey items or insects to target, archerfish cannot perform this fundamental aspect of their natural repertoire. Their sophisticated neural processing — evidenced by face recognition and physics compensation — suggests a cognitively complex inner life that inadequate captive conditions fail to engage. Research on archerfish cognition has transformed understanding of fish intelligence, with direct welfare implications.
