Hawaiian black sand CUC

[erin10885]

I have an IM 40L AIO for my office tank with Hawaiian black sand in it. I currently have snails, emerald crabs and hermit crabs for a clean up crew but really need something to turn the sand over. I think the gravel/sand might be too big for a goby to handle but I'm not sure. Any suggestions are appreciated.
