Identification and Names
A concave upper profile runs from the snout toward the dorsal fin. This entry retains Adinia xenica, while modern references also use Fundulus xenicus. The changed genus and ending should not be mistaken for a separate fish without checking the synonymy.
Very Shallow Water
The species occurs along the northern Gulf coast from Florida toward Texas. Many observations are from less than thirty centimeters of water. Such margins can be missed by surveys aimed at deeper channels, despite being valuable fish habitat.
Size and Life Cycle
The maximum length is six centimeters including the tail. Diamond Killifish is not an annual killifish dependent on a seasonal dry-pool egg stage. Its tolerance of a wide salinity range also does not mean every population experiences the same conditions.
A New Combination of the Same Name
Adinia xenica and Fundulus xenicus are names used for this fish. Retain the original label while recording which taxonomic treatment a source follows.
