Starry Blenny

[ilikefish34]

Currently DD is offering a bonded pair of Starry Blennies. One is listed at 4'' and the other at 2 1/4'' but not as male and female. Does anyone have any information about sexing these fish or is it just trial and error? Or try mixing sizes as one would for many Goby species? I ask because I have one now and would like to pair it up after I upgrade from the 125 gallon.

Thanks
Mike
