Who's digging up my sand?

[rrasco]

I have something digging in my tank. It likes to excavate little burrows under the edges of the LR on the sand. I'm not sure who is doing it. It's not harming anything, just kind of curious since I didn't think I had any burrowers.

Fish list:

Kole Tang
Flame Angel
Royal Gramma
Occy
Cleaner Wrasse
Flasher Wrasse
Green Mandarin
Lawnmower Blenny

do you notice the tunnels popup during the day or during the night

[rrasco]

At night.

I wanna say it's your wrasses, they like to burrow at night.

I have not had them that long, only a few weeks. I had noticed some digging before, but think it was just my tang picking around. If I had to, I would say it has gotten more noticeable since the addition of the wrasses though.
