Biologi     Ordlista (t.ex. epibenthic)

Found in bays and estuaries among submerged vegetation; diurnal (Ref. 4281, 30915). Can tolerate salinities from 1-59 ppt (Ref. 30915). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Length type refers to Height (= from top of coronet to the tip of straightened tail). Breeding in the aquarium is possible (Ref. 130565).
