I'm considering getting a species of sleeper goby, but am curious whether it will bury things on the sandbed while feeding. What has your experience been?
It doesn't collect frags like a jawfish. Just moves around and makes burrows under rocks. If a burrow came out right beside a small frag next to a rock it could fall in. But I can't say that I have had it happen. These are pretty easy going fish. I plan on getting another one for may tank at home.
