questions about Diamond Watchman Gobies

[USCavalry19d]

just kind of curious about the Diamond Watchman Goby. i bought one for my 75 gal tank however, he never comes out of his hole that he dug under a rock. im kinda worried that he might starve or something since he never comes out to sift the sand or eat. would it be wise to maybe get another so that this one doesnt get bullied by the other fish as much? my other fish are as follows:

1) 1 Yellow Tang about 4-5 inches in size
2) 1 Saddleback clown about 4 inches in length
3) 3 4-stripe damsels each about 2 inches in length
4) 1 copperband butterfly about 3 inches in length
5) 1 Diamond Watchman Goby about 3 inches in length

This is pretty comon behavior for watchman gobies--they stay inthe burrow, even if they aren't threatened. Adding another one won't change that behavior, and may in fact result in fights between the two.

Make sure some food falls near the opening of the burrow, so he can dart out and get it.

Make sure he can't jump out, for some reason they seem to like to do that.
