Thanks for the replies! I am trying to come up with a good aquascaping plan in general, not sure if I should slope the sand bed or do a uniform DSB through out. I have some smaller grained sand and a bit of reef sand with lots of shell rubble for burrow building. I think I will do 4 inches if I do a unifor bed, possible deeper if I slope. I will post some pics for sure once it is all set-up. For now the only tank mate will be a Yasha Hashe goby who is being bullied in another tank, should be a nice timid tank mate for the jawfish, at least that is what I am hoping for. I have also read that rotal grammas, small gobies and many clowns make good tank-mates.
