Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 10 - 15; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 11 - 13; Ryggkotor: 34 - 37. Branchiostegal rays: 5-6 (Ref. 36572).
Commonly found in bays and salt marshes near shore, may enter freshwater (Ref. 36572). Often used in laboratories for environmental studies. Not a seasonal killifish. Is very difficult to maintain in aquarium (Ref. 27139). Oviparous, with micro-nektonic larvae (Ref. 36572). Single demersal eggs are attached to spawning substrate via small weakly adhesive filaments (Ref. 36572).
