Riproduzione
Qui una piccola nota su uno studio svolto sulla possibilità di ottenere la sua riproduzione anche in acquario: "This specie uses an indirect reproduction necessitating a larval stage in brackish to even salt water conditions. The ten (sic) larval stages of this specie are documented by Wayne Hunte, published en 1979. This study was realised in a 1.5L volume (one larva for 15cm³), with a well oxygenated water at 32 ‰ salinity. The food used was wheat-germ and Tetramin in portions and with an adapted size. All but the two first stages where the larva do not feed, the feeding occurred every 12h, and water was changed every two meals. Up to the fifth larval stage, the evolutions are perfectly distinct one from another. The following stages are more arbitrary, determined to make the important morphological differences evident during the larval development. This development takes a minimum of 53 days, and a maximum of 74 days, from the moment the eggs are expulsed."
