Guys, just to share that i do have this blenny in my sps frag tank and have not seen it disturb or nip at my sps at all.
What i have observe is that she will go around nipping on life rock for algae, nothing more. I have seen other reefers sps tank with this fish as well, no problem.
I am more incline to believe that there are some form of "acquired taste" behavior of this fish ( in fact for some pigmy angels too ), i.e. they may have already acquired a taste for sps and beginning to treat it as a source of their diet.
Hence it may be a matter of hit or miss for this little cuttie
However, do take note of the more 'notorious' species like Leopard Blenny, they are almost a certain to making your sps their happy meal , so it's a NO NO for this one.
