not sure if its what your looking for but, any of the spiney eel species
(tire track to fire spot) would make a nice addition to the tank.

the spend most of their day burried in the substrate and i think soft
sand would make a perfect home for them. their tough and aggresive
enough to deal with your jewel too.

should churn up your sand as well as adding a little bit of mystery
to the tank
