Purple Dottyback digging?

[MrAlpha]

So I have had this Purple Dottyback for about 3 years and he has always just stuck to holes in the rock work. However, the last couple days he’s been taking mouth fulls of sand from behind the rocks and spitting it out in a couple different parts of the display. I wish I could see if he’s digging a burrow or something back there. It’s not really a issue I was just curious since he’s never done this and I didn’t think Dottybacks were diggers.

The only think that has changed recently is the addition of a bicolor Blenny the week before. I haven’t seen any agression between the two.

Here he is admiring his handy work

Yes, they can do this.

Nothing to wory about. It isn't an elaborate burrow or den like some fish have, but rather just a refuge.
