Its stragne.. because Guy (Yellow Tang), seems to get aloong great.. they dont fight or anything.. it seems that they even like to eat together.. as soon as Lenny starts biting away.. Guy just comes over and starts eating with him.. they seem to be good friends.. :)

good friends... or fierce competitors :)

good friends, or your blenny is smart and dosent want to get tagged by your yellow tang, yellow tangs are mean buggers too...
