I see like spider webs at the base of my acro .and with a magnify lens i see a hole where it lives and somethig white with 2 pesky antenas peeking out the hole .now where this bug lives its has eaten the coral .5 inch i a circle ,had this bug for about a year and tried to drill the hole out where it lives i thought i had him, now the acro is part of my live rock ..any thoughts without a picture what it could be ? And should i leave it alone ?
