Ok so i recently discovered brittle worms in my tank i think i got them from a rock i bought from someone ive gotten them in the past when i had a 20 gallon so i emptied my tank threw away all my sand and soaked all my live rock which was only two big pieces in hot water then picked them all off. Now I see them in my 55 gal but now i have quite a bit of sand and rock so how do i get rid of them, I actually saw my tang eat one of them the other day which was weird. The rock i bought also popped out some aptesia now its spreading i read that certain shrimp will eat it, is that a fact?[IMG][/IMG]
