I have been missing fishes every once in a while. Tonight, I saw my blue tang which has been missing since morning. I twas half dead. The same blue tang was swimming and feeding actively last night.
To my horor, I soon saw my algae blenny swimming to the blue tang and bite it. The blue tang frantically tried to swim away but the blenny gave chase. Is algae blenny known to be agressive? Liveaquaria classifies this fish to be peaceful. I also have a smaller scorpion blenny. Is this fish also agressive?
