What predator fish can go in 150 gallon

Redfin and grass pickerel; marbled bullheads, would be a good size for your tank or smaller. If you want to do something really interesting skip fish all together and get some tentacled snakes instead.
Exactly right.

Or you can get a black crappie and few big American bullfrogs, bullfrogs will lunge for anything they can cram in their mouth (such as flying birds), and can be trained to be handfed.

Bullfrog in a 150 with a black crappie? Sounds good, what could possibly go wrong lol
 
The problem is your width. It's good for cichlids, but your in that odd place of really needing a wider tank to have true oddball monsters. If your up north piranha would be my go to as mentioned. Aside from that maybe a bgk, smaller polys, or something like that
 
That reminds me that there are species of stonefish and Moray eels that people keep in freshwater. Those would be really unique and if you only increase the gravity to about 1.002 the maintenance would be the same as full freshwater. So you could have a stonefish/Moray eel/archer tank

The moray maybe you are thinking about gymnothorax polyuranodon? These can be kept in full freshwater.

Then there's the freshwater archer fish, Toxotes blythii, which will thrive in full freshwater as well

Not much unless one jumps out, crappie don't eat or bother adult bullfrogs.
Of course black crappie wil eventually outgrow tank.
