That is really interesting. They are rumored to be difficult fish, so you must really be doing something right.
And in that small of a tank, they don't seem to be having issues with damaging their rostrums?
So far they don't seem to be hurting their rostrums much, a couple have a tiny white flat spot at the very tip but other than that no problems. So far I've seen them grab a sunfish three times but only one was swallowed, I'm not sure why but the other sunfish that were grabbed turned up dead the next day. I am quite certain a school of minnows or shad or similar small fish would be a prey item for an adult paddlefish....

What you're seeing is the paddlefish discovering their mouth. They're probably showing more signs of filter feeding too. They get another fish in their mouth, always face-first, chomp down, break its back, and spit it out. Before we started culling the runts, we had a 15% kill rate at this point in their grow out. The first time this happened, we were devastated.
This behavior will stop in two weeks. Don't be surprized if you find a couple of smaller paddlefish dead this way. Pick up the dead fish by the head. You will notice the broken spine area directly behind its gills.
And, no, I have never seen a yearling jump. Older fish jump at dawn and dusk. If they swim with their paddle out of the water, you have water parameter problems.

I added one cup of marine aquarium salt and 1/2 cup of calcium chloride to compensate for the extreme softness of the water. I am aerating the water for 24 hours before adding filtration or fish. I'll put up a you tube video of the fish in their new home in a few days...
I added some sacrificial fish today before adding the paddlefish.... Gambusia... they died in a few hours, I guess either the H2O2 is still too strong in the water of the HS is still there. Maybe in another 24 hours it will be ready... I want to get this tank going!

At the other end of the tank is a piece of bog-wood with two slender peaks and two hollows. it looks like a tree was torn up out of the sand this was what is left. A long arch shaped bog wood limb about 18" long goes across the back connecting the two ends of the aquarium. I can tie some plants to the wood at some point. I'll post pics as soon as I decide on the exact arrangement but right now the cluster of three rocks with the one piece of bog wood at the other end looks good...
The wood and rock work is low and leaves plenty of swimming room, I'm thinking of a Marineland 400 filter for the tank, does anyone use this type of filter? I use the 200 and it works pretty good is the 400 was reliable? I'm going to put the filter on the end of the tank instead of the back so the current goes the length of the tank, the paddlefish seem to need a strong current...
