I was at the LFS
today and picked up what he told me was a diamond goby. I had been looking for a small sand sifting goby for awhile (really wanted a randall's) and he told me this one wouldn't get too big for my 40gal breeder. I should have consulted my books first but it was a nice looking fish so I brought it home. Now I have two problems:
1. When I got home I got him in the tank and got my reef fish guide out to check out the particulars of this little guy. Now I am a little worried because it has blue spots on the cheeks like the picture of the orange spotted goby which this book says can get up to 8 inches long! Currently it is about 3 inches long
2. It started doing the sand sifting right away but then went straight for the hammerhead coral I have on a nice flat rock on the sand bed. It is one of my favorites and It won't work as a burrow since it would just fall in on the goby. So I moved the coral, put the sand back and figured it would try somewhere else. Five minutes later it was right back under the ever sinking hammerhead.
My question is: Does anyone have a good trick for catching a diamond goby in a reef tank? I went in with the net and within seconds it was lodged deep in my rockwork. Lesson learned - listen to the LFS
guy but never trust him without prior research.
