Aquarium Advice Activist
Aquired some live rock that I transported in a sealed box when I checked for any 'intruders' i found this.........when I removed it 'it' was very stubborn and broke in half.......as I further attacked it 'it' started to glow illuminous blue in aggression. Both halfs are now in my garden been eaten by a bird no doubt....but I wondered what it was. I have seen bristle worms and if it was on of those it was obviously on roids and not suited for my tank!
