Nafe420 Posted May 12, 2014 Report Share Posted May 12, 2014 So I've always wanted a Jack but have a few questions before I commit to one. To start a young one would my 4x2x2 or 5x18"x20" be better? How long would a 6cm take to outgrow one of these tanks? Do they ever eat pellet or usually live/dead bait? And being so young, how long would it take to convert brackish to fresh? I understand I will eventually need a monster tank, anyone with experience growing these out I'd love to hear some info. Cheers Link to comment Share on other sites More sharing options...
presto Posted May 12, 2014 Report Share Posted May 12, 2014 Hey mate I had one from 4 cms to 50 cms . Went from 2ft to a 4ft then a 6ft in the space of 2 yrs. mine took pellets but loved live an dead food too. Mine was fresh when I got it . As far as I know there easy to convert as long as you do it slowly . Mine went from fresh to brackish as he got older . They do better if brackish water when there older . Like any fish the more you feed them an change water faster he will grow . Link to comment Share on other sites More sharing options...
Nafe420 Posted May 12, 2014 Author Report Share Posted May 12, 2014 True that's almost as fast as a Barra I had. And yea think they head for the ocean when mature so that makes sense. Thanks mate Link to comment Share on other sites More sharing options...
