Check your snails often helps. Check your clams if you have one.
The BEST i've done to get rid of them is pulled my sand bed. That really lowered their numbers. I have a 6 line wrasse also, they are "supossed" to eat them :notsure: . Yellow wrasse eat them also.
Ive been pulling mine out 1 by 1 for the last year and half.
Ive lowered their numbers by hundreds
but still see a few from time to time. In the begining it use to look like my rocks were covered with rice when the lights would go out. :scared: I also got a 6line but dont know if hes eating them :notsure:
