My Yashia Goby

Cute looking fish but it does need feeding up. He looks very skinny, unless it's the angle of the photo.

With regards to pistol shrimps making a noise, yes they do!!:) I have one in my 180 gal which is downstairs and sometimes I can hear him firing away when I'm upstairs. I certainly wouldn't want one in my bedroom;)
