SUMMARY.Aphanius dispar was observed in the field and some simple laboratory studies were undertaken in Oman. A. dispar is almost totally ubiquitous in all bodies of fresh water where it occupies a wide range of habitats differing in stream flow, water chemistry, temperature and substrate quality. It often is found in association with one or both of two cyprinid fishes. Cyprinion and Garra. Aphanius is tolerant of wide ranges of salinity up to full marine water and has a wide temperature range. A. dispar resembles Cyprinodon species in a number of particulars, probably reflecting phylogenetic relationships and a common evolutionary response to desert conditions. It breeds throughout the year with a probable peak in the months of April to June.
