It's recommended to have a substrate with a variety from sand grain size to large pebble size for jawfish to make their natural burrow structures.
Have no fear tho if you only have sand.
They will still make burrows under and inbetween your rocks with no problem.
Only problem I've found with jawfish is that it's sometimes necessary to target feed them, which if they burrow behind your rockwork where you can't see them is darn near impossible.
