Yellow head (blue cheek) sleeper goby

[Scavenger]

Hi all,

When I upgraded from my 20 gallon starter reef to a 46 gallon, I desided to have a sandbed rather than the crushed coral I used for the 20.
When I set it up, I put a layer of the crushed coral and coral rubble down in the areas I figured all the rocks would go. I then put the rocks down on top of this and spread my sandbed all around the rest of the tank.

I figured this would reduce sifters from sifting under my rocks and provide a more stable reef structure. NOt to mention that it would seed the tank as the crushed coral was quite alive.

I then figured I'd need a sand sifter or 2 to keep things happy and clean. I elected to go with a yellow head sleeper goby to do this because all my reading on them said they were good at this and were a peaceful inhabitant. The only negatives were that they kicked up sand and burrowed. I figured I could live with kicked up sand and burowing shouldn't be much of an issue.

Anyway I just heard about how these fish will chase down hermit crabs and other bad behaviour. Thanks to Bob I and Namscam for the heads up there!!!

Anyone one else want to share goby experiences so I can learn what I have to look forward to or take preventative measures??
