New bottom dweller

[MaiReef]

Already in 100 gallon mixed reef tank...
Engineer Goby(full size) - only sifts(removes sand) under the rocks
Solon Fairy Wrasse
Flame Angel
Coral Beauty
Gold Striped Maroon Clown
Scopas Tang

I would like a fish or invertibrate that will be out sifting or just swimming along the sand. I had a diamond goby and it eventually stopped eating after 2 years got very thin and died. I would get another, but I really don't like killing fish as I would rather have them die of old age. I think the Cleaner shrimp was eaten by the Engineer. Once the Clown got his RBTA there is no major aggression in the tank. The biggest thing is he chase the Wrasse away when the wrasse gets within 6 inches of the Anemone. Everybody is fat and seems happy, but since the Engineer stays under the rock except for feeding. I would like a fish to be out and about along the bottom. Please send possibilities. Thanks.

Maybe a watchman goby or a scooter dragonette?

I am trying a Picture Dragonet. Things are going well in hour 3. He hasn't eaten, but is settling in. The LFS red him Cyclops, rotifers and plankton. He had been there since October so I hope he does well. I do have a refugium and pods as well.
