Rumpig Posted January 19, 2004 Share Posted January 19, 2004 Gidday Thermo, Sadly M. jacks are in the same catagory as many other of Australia's natives with their breeding habits, migrating to saltwater when they get the urge to spawn. Therefore unless you have facilities similar to Sydney aquarium you'd be hard pressed to breed this species. Mick Link to comment Share on other sites More sharing options...

Mick You could try progressively increasing the salinity, and altering the water temps, I have heard of this working in breeding Australian Bass, so perhaps it would work with Jacks.

Barra Posted January 22, 2004 Share Posted January 22, 2004 i would very strongly advise against putting 2 MJs in a 4x2x2 its just not big enough i have seen an MJ at 80cm in an 8ft tank the guy was offered 6000 dollars for the MJ but he declined Link to comment Share on other sites More sharing options...
Peter_Gun_Riff Posted January 22, 2004 Share Posted January 22, 2004 i say the bare minimum would be a 7x2x2 for a pair as they get huge Link to comment Share on other sites More sharing options...

And at that size they generally migrate out to the reefs and are then called Bass jacks(or somthing like that.) Just some useless info for ya's Link to comment Share on other sites More sharing options...
