I don't plan on ever getting mine of of live food.
I do plan on getting him hand fed and on to dead stuff. But not off of live food. Studies show that fish that hunt in the wild do better when they can hunt on their own. I have a year round supply of minnows and they are free in the summer, I fish a lot.
If you look @ the pix in my thread "pix of my gar" you will see how bare the 55 G tank is. it's to keep him with enough room..
And not to hurt his self thrashing around when he does hunt. He's way faster on a side swipe then any Oscar or Jack Dempsy I ever had.
OHIOMFK gives great advice here.

And my thread "pix of my gar" to see what OhioMFK is talking about with tank setup.
I keep it bare and open so he can have room to strike. The Gar side swipes faster then any Oscar or chichlid strikes period.
I also have 3 sides of the tank blacked out with a garbage bag. both sides and the front. this is so he knows where his space starts and stops.
Also The tank is located next to the entrance between the dinning room and kitchen so there is a lot of foot traffic. I don't want him spooked as there are 4 kids the wife and me.
So far the bag is working, no one has seen him dart once, he just glides around.
He also spends over 50% of his time up top in the floating plants.
These fish don't need magical care, just the right environment to live in.
Another great tank setup is Lepisosteus's 220 tank he had them in.
good cover but lots of room to move. ( I hope my 150 looks 1/2 that good)
I did a metric ton of reading on these guys before I sought one out.
Then found this place and did what you are doing.
Sought real world advice from the guys that have them.
