I put a bunch of Fishdoc's frags in my previously coral free nano last night. My yellow and green clown gobies went to town on the frags. They were just burying polyp after polyp as they moved and perched from 1 frag to the next.
I gave the yellow clown goby a second shot in my larger tank and it was the same story, if not worse as he worked the larger acro small colonies I have. I now have both sitting in the net in prison.
It was amazing to see the fish feel even more at home and act more like it would in the wild. Sadly though, I don't have large enough colonies to house the gobies at this point. There is no way the frags could handle this abuse. Off to the fish store these little guys will go.
I have to say, yellow clown gobies are fascinating though...I never thought I would like a 1.5 inch fish so much but these guys are cool...If you don't have SPS, get one, especially if you have a small tank. They are very entertaining. I swear the yellow guy never slept even at night, he was always bouncing around....Very cool fish, especially for size...
