I love the picture of the diamond back goby. He looks just like mine(there's a suprise!)
I have a sand bottom and he filters it all day. You substrate looks more course than live sand , does he filter that through his gills also? Ouch! Great pics!
Yes, Pedro sifts through everything. I've even seen pellets go through. :notsure:
Here's another picture of my sea urchin Boo (aka Bulldozer). He's taking one of my shells for a ride in this one.
