Well, I have seen a movie once with jumping seahorses
As Bruce said wrasses are known to jump for no particular reason.
The Springerii or Marbled damsels or any kind of damsel will do so now and then to take the jump.
Hence every fish will jump

Just think about this where these fish come from they are free to jump as in 99.99999999999999% they end up back into the water.
Now in our glass boxes that can be different and the fish just don't know.
Damsels can hide pretty good too.
I had about 10 springerii damsels in a open frag tank with plenty of hiding places but I have seen them jumping, lucky it was a LARGE frag tank as they ended back up in there.
How long ago did you add this Sprigerii?
Any other fish in the tank?
Does you light come on a set schedule?
What size is your tank?
Do you plan on going to the McKinney October fest this year?
Any pics of your tank?
What kind of food you feed your fish?
