Black Cap watchman goby?

[saltyhog]

I've been racking my brain trying to figure out why I have sand spread in three places. On one particular rock, on my largest RFA and on a good size colony of Nuclear Death palys. I knew the locations were not places my small A. randalii pistol shrimp could put sand but I had no idea who was doing it.

This evening I did a water change and moved some sand up against some rocks where it seemed to be disappearing. A little while later I spotted my big Black Cap basslet doing this...LOL



I guess he didn't like me blocking the entrances to his cave. :D

Aha! I would say guilty as charged! :D
