freshwater red snapper?

[killerfish]

i was just about to say i think you saw a mangrove jack didn't know they got 4 feet new they got big but thought it was more like 2-3 feet

they are high end brackish fish so no i wouldn't keep them in freshwater it really bugs me how LFS allways try to sell brackish fish as freshwater fish but they are pretty aggressive with a mean set of teeth great fish for a SINGLE fish tank

I bought a mangrove jack a while back at 3'' and got to 15'' in bout 18 months. Nastiest fish ive ever had. It killed 2 flowerhorns (1 the same size as the jack) a Barcoo Grunter and nearly a large chocolate cichlid. I busted the jack dragging the chocolate cichlid around the tank by its head, then i decided i had to get rid of it. Also it was the fastest feeding fish i have ever seen! I would throw 10 or so prawns in the tank and the jack would eat half of em before any other fish would even realise there was food there.

Jacks can live happily in freshwater, just the same and salt water. we have them stocked into freshwater dams over here, and they power on!!

It's difficult to compare survival stats in the wild to those in aquaria. Mangrove jacks have a hard time in FW in captive conditions due to rapid water chemistry shifts and increased stress from being more exposed. However, I've seen large aquarium specimens doing well in very large FW aquaria with over-sized filters and good maintenance. These aquaria were balanced to the heavier side of alkaline pH levels.

mongrove jacks usually when smaller live in brackish water when young and then go to deeper ocean waters from what i have seen and caught. You will find them up to 3 pounds in shallow waters but they will go to 50 feet after that so i think you would need the saltwater eventually.

thank you for that. there are 2 species that can live in pure freshwater,

L. argentimaculatus
L. goldei

both are found in australian waters, and the latter only around Aussie/New guinea I believe
