Adult GSP are supposed to live in freshwater? (Study)

Post by EughPuffer »

I found this study from the National University of Singapore. It says that adult GSP are found natively in freshwater while their juveniles are in brackish water. But from what i read online from other sources, they say to increase the salinity of the aquarium as the GSP ages. I'm not sure I understand if we should add salt as they age or reduce the salinity? Since, naturally they would move from brackish as juvenile to freshwater as adults. Can anyone explain?

Adult GSPs thrive in marine conditions & become sickly &with shorter lifespans in FW, in captivity.

That's strange..... why do they move from BW when their juvenile to FW as adult in the wild?

I also visited a fish store and they sold both juvenile and adult GSP. They told me that they keep the juveniles in brackish while the adults in freshwater. They didnt breed them. They captured them from the wild and sells them. And they captured the adults in fw and the juveniles in bw, so they just kept them with the same water conditions in the fish store.

I've not read them being in marine water. Can they live in the sea too?

Adult GSPs often move from FW-SW & back in a day. Captive GSPs are best kept in high-end BW to SW.
