I have kept many jawfish, Right now I keep a rare red jawfish.
First thing with jawfish especially with the blue spotted is cover the tank it will jump out, this is not a if it will jump out.
Already been said blue spotted are a little more touchy..
They require different grains of sand and small rubble..
pvc caves sometimes work and sometimes do not..
Do not keep with other burrowing or sand moving fish. Some gobies will kick them out of their home and steel them.
Jawfish can be very shy and sometimes can be massively stressed out before finding a place to burrow and building a burrow.
