That's what I thought. Hopefully he's not going anywhere any time soon, I adore him. Now I'm worried, search says 2-4 year lifespan. I've had this guy almost 4 now!I think blennies are so cool. Since you have a bi-color already, definitely pass on another addition. They'll fight. Urchins should help keep rocks maintained. Fox should do most of the work.
I'll plan on my tux, fox, bicolor keeping any stray algae under control & go from there if it doesn't work out.
