I was at LFS tonight and saw a very nice, nice color and healthy, Royal Gramma that I was going to purchase. Well the fish went into the overflow through a crack, no big deal. The tank has a few pieces of LR and has a bunch of Bristle Worms. When the fish was bagged if must have run into some of the worms and had a bunch of bristles sticking out of its lower lip. I did not purchase the fish because I did not know how they would affect the fish.

1. how would the bristles affect the fish?
2. how long should I wait to see if LFS still has fish to try and purchase?
