Jimbo7, nice to see this topic approached. I have recently purchased one of these. Name is sunshine and I have to say I can't believe he is still alive. I was in my LFS
and that day a few of them arrived. My guys there told me to wait until at least the next day to take one home. So I showed up the next day. I wasn't paying too much attention as to how sunshine looked, but within a few days it looked as if this goby has shrunk and most of the time looks like a skeleton. So I figured, this one is not eating and will only be a matter of time. That was almost 2 months ago.
Still looking somewhat skeleton, sunshine cruises around the tank and pretty much lands on everything.... expect for the BTA and bubble coral. The most common resting places are my fox and duncan (20 heads). Once in a while, on my rock full of brilliant purple mushrooms, and I have never seen such a vibrant display of yellow when resting on the purple.
As for eating, not sure what's going on. I also use cyclopeeze but there is so much happening in my tank when I feed that, keeping track of sunshine gets tough.
I have not noticed any corals getting 'annoyed' because of this addition. Maybe too early to say, but so far so good.
