I have been doing some research on different blennies for my 32G Biocube and I was interested in the Barnacle Belnnies due to their nature to hide in the rocks and dart out, but I have noticed that many genus of blenny also seem to have the same base behavior. Is this something that is characteristic of the larger blenny grouping as a whole, or just to particular dsubspecies, or just the barnacle blenny? The barnacle blennies seem to run at a higher cost for a smaller fish than some of the others I have looked at and I am trying to decide if it is worth it to spend more on 2-3 Barnacle blennies, or go another route with a more colorful belnny that would demonstrate the same unique behavior.
