look, i do worry about my tank esp when i have both a plate coral and a diamond goby. but i have not seen my goby burying my plate coral at all. it's all fish personality dependent. other than plate coral, i have other corals on the sand bed, but as of today i have not seen my goby burying any of them. as matter of fact, when the goby sees the corals on the sandbed, it actually is smart enough to move away from it. i have no experience with jawfish, but last time i check they're different. i don't know others' tank setup or the space they have for the goby and the corals on the sandbed, but if you give the goby enough space, it won't spit sand right on top of the corals or clams. also, in this hobby, what works for one person will not guarantee the same method will work for others. you can call me lucky, or the fact that my goby is smart, or both, but so far, my corals are doing fine.
