Murray Cod

I recently obtained a 4cm Murray Cod Fry which I put by himself in a 20 litre tank and have been feeding twice daily with NLS in the morning and Frozen Brine shrimp in the evening. He initially hid all day and darted out only to eat. I have been doing 25% water changes twice weekly and in 6 weeks or so he has quickly become an 7cm fingerling and much more interactive and visible, he "recognises" me (his food source) and patrols the territory of his tank that will soon become too small for him I would think.
Has anyone got any tips on growing these guys up? Is he the same as most fry/juveniles? Lot of high protein and water changes? I believe they are slow growing by nature but mine is shooting up at the moment. I believe they are very shy and jumpy as juveniles. At what stage could they temporarily be put in a larger tank with fish around their own size? I understand that there is eventually a stage where this guy will become most unsociable and will require his own large tank. Looking forward to that day!!!
Just interested if anyone has any experience growing these guys up or are keeping an adult specimen? I find them fascinating.

Muz is about 12cm now and enjoys a choice diet of culled Malawi and Tang fry (twice a week) along with NLS Cichlid Formula every morning. I don't want to feed him exclusively live food as I have heard that predators can turn their nose up at pellets to the point of starvation if live food is what they are accustomed to. This guy smashes anything live that goes in the tank. It barely hits the surface and BANG! I probably wouldn't buy or intentionally breed fish as food, that is not me (each to their own) but I do have to cull the fry I have and it's a convenient situation for him. I have to admit it is impressive, but there is rarely much natural stalking to watch. Occasionally the first strike is off target. The second one never is. He has learned that when the lid lifts, something tasty is going in.
These guys are great fish to grow up. Prettier than Barra and more confident at 10cm.
He's going to need his 3rd tank soon...
I will post some pics when he is in his next tank...

Considering he is only 12cm or so, he chomps 3cm offerings in the blink of an eye. Ruthless and efficient.
I remember seeing one about 5 foot long in Sydney Aquarium a few years back, but I'll cross that bridge when I get to it!!!
Where do you get massivore pellets.... just out of interest?
What happened ice?

my mates 30cm cod, belted a jardini (40+ cm) to its death over night, tried to eat a 15cm bullrout, and would attack the gravel vac etc, these guys have attitude as they start to grow, mate gave it away as it was a bit boring in a 6x2.5x2 with the one fish.
