Arabian Toothcarp

Aphanius dispar

Also known as Mother-of-Pearl Fish, Arabian Killifish, Striped Toothcarp

Arabian toothcarps are remarkably hardy killifish adapted to survive extreme environmental fluctuations, thriving in hypersaline lagoons, thermal desert springs, and shallow coastal marshes alike. Males display shimmering iridescent vertical bars and broad fins during courtship, fiercely defending small territories against rivals to attract drabber females. Their voracious appetite for aquatic insect larvae makes them key controllers of mosquito populations in arid aquatic ecosystems across the Middle East.
