Hello Gr8KarmaSF, i am feeding them some smaller fishes but i gotta cut in little pieces, otherwise they canot catch to eat. my tank to keep them is 30" L x 18" D x 18" water level.

I don't know who told you the paddlefish will only grow to 2ft. I hope you're ready to move him to large enough quarters in the near future. These fish grow to an average of 154 pounds (70 kilos) and lengths to 8 feet (2.5 meters).


Paddlefish are filter feeders. Live/frozen daphnia, brine shrimp, mysis shrimp, slow sinking crumbles, FD krill/plankton, mosquito larvae, and fish fry are fine for feeding to these fish. They'll even quickly learn to roll upside down to take floating food from the surface.

looks like a battering ram to me. lol I bet they can break though glass

the size of it is really huge. i will get really to move them (2 of hem) to my bigger tank. (70in x 25in) and give them a comfortable space...hopefully it is ok. otherwise i got to make a mega tank...

As they grow, just keep in mind that a quarter of their length is inflexible bill. They're also constant cruisers. So, they're going to require a tank that provides a large swimming area (and feeding area) and a depth (front to back) that allows them sufficient room to turn without glancing/hitting the tank walls.
The best guide, for housing these fish, is to provide a tank a minimum of twice the length of the fish and 1.5 times the fish's length in depth of the tank.

(as adults, this translates to a 16 foot x 12 foot (4.9 meter x 3.7 meter) tank/pond)

The last 4 that I kept were grown out on an 8ft diameter vat then, transferred to my 34'x22'x2-5' pond to occupy the top portion of my sturgeon pond.
