I can maybe grab a pic tomorrow when my lights come back on. I feed my clean up crew pellets because I have a very low bioload and there wouldn't normally be enough
detritus to support them. In exchange they keep everything clean and are fun to watch. I haven't heard of the Stars dying from starvation personally, but I am sure it can be a problem.
Also, I have a deeper sandbed and the star doesnt bury itself more than a quarter of an inch at the very most.
