This specific kind of jawfish isn't easy to keep at all for a number of reasons. No 1, you absolutely need the entire tank top to be covered. Egg crates won't be enough as they can easily fit through the 0.25" spacing. No 2, a lot of them don't acclimate well and will suffer and die from blue spot jawfish disease, which is whites patches on its body. It's a weird disease and that's why it has its own name. No. 3,!it is very skittish compared to other kinds of jawfish and cannot compete for food with active fishes like tang and Angels. No. 4, it prefers to live among a mixture of coarse and fine sand plus other small shells and rocks. Such landscape is hard to come by therefore its long term fate in a reef isn't good. It also spits out sand at fish and at corals and is constantly moving and making new homes and underground tunnels, thus potentially making a messy for your nice aquascape.
I love this fish, don't get me wrong as its not only colorful but comical. I just think it is better off living in its own FOWLR tank.
