*This is a very active species that will pace from one end of the aquarium to the other. It will occasionally stop to probe a reef crevice with its snout or examine the bottom as it searches for food. As it grows, it is not uncommon for male Bird Wrasses to develop large bumps on the snout. These protuberances, which may be fatty tumors, do not tend to interfere with the feeding and general health of the Bird Wrasse. *
