Is there a diffrence between a bristle worm and fire worm i got a candy cane coral today and it was really nice. i knew it had one aptasia on it but was willing to buy it and just kill the aptasia. well when i put it in the tank this large pink worm with white bristles crawled off the coral and into my live rock. i was not worried about a bristle but i was reading some bad things about fire worms. same, diffrent, anything to worry about.
