Description
The Spotfin Killifish is a small, slender fish native to the Atlantic coastal marshes of the eastern U.S. Males display a distinctive black spot on the dorsal fin and can show more vibrant coloration during breeding. They are euryhaline, adapting to both brackish and freshwater environments, and are best kept in species-specific tanks or with very carefully chosen tankmates.
