Didn't think of that, thats a good point. The barnacle blennies should be going in first so maybe they will claim them first. Maybe adding a second cluster could help. I'll definitely keep this in mind.Hum. I will say every single blenny I have had has lived in the barnacles when they discover them. I had a bi color and lawnmower brawl over one cluster (when I had one at each end of a 6 foot tank) and had to remove one! I would just keep an eye on it since they all seem to love barnacles!
