Flow to high for horseshoe crab?

[J_Gard88]

Just picked up a horse shoe crab from my LFS. He seems to be doing fine but once he lets go of the rocks or substrate he just takes off and blows around the tank, and even when he's not in high flow areas he swims around until he ends up in the jet stream again. Is this normal? Do they like to move around alot???

They never stop moving. Why yours enjoys the jacuzzi I couldn't speculate.
