I was gluing a frag to some rock and my Achilles came right over and picked at it. Got a chunk of Frag glue on its mouth. I was trying to catch it - but it is impossible in my tank with my rock work. It is swimming around and rubbing the glue on rocks trying to get it off. Of all fish... ugh - how can I help it or will it eventually knock it off? I guess that is what I get for hand feeding them.
