I had two healthy, active Engineer Gobies, about 5.5-6 inches long. They both ate well, and were pretty active at night and would come out from under the rocks at feeding time.
A couple months ago, I made a mixture of DIY coral snow as suggested by @SunnyX

I have dosed this 3 times, dosing a less amount than suggested. I have done nothing else different.
My two Engineer Gobies have since died. Everything else in the tank, including fish, Coral Banded Shrimp, snails, hermit crabs, and coral, is fine.
