I have a pretty well stocked 55 loaded with coral and fish. I just recently, two days ago added an orange spot goby. He's been non-stop sifting my sand and making caves and LOTS of dust. My water was super clear it looked like bottled water, now it's constantly dusty. Will my new goby slow down on the sifting? He has in two day's sifted the intire tank, even under rocks and has no respect for my corals and frags he's been burrying. I love the little guy! Will he chill out eventually?
