My little diamond goby snuck between my lid and found him in behind my tank all dried up. Given the unfortunate opportunity, I am interested in getting a blue-spotted jawfish. I think they have the coolest personality and are pretty hilarious to watch. My tank is a 6ft x2ft. Are jawfish and gobys compatible? I really need something more than my 2 conchs and nassarius snails to clean my sand but want a jawfish as well.
