Mantis Shrimp/ Bristle Worms

I'm getting ready to set up my tank and I've been doing some research on live rock. I keep reading that you don't want Mantis Shrimp or Bristle Worms in your rock. Why not? Are they harmful? Thanks.

Mantis shrimp kill your inverts and I guess from other posts can grow big enough to possibly crack your tank. Bristle worms are not ALL bad. Depends on what kind of corals you want to keep because I guess they eat some. Arrow crabs will eat bristle worms.

mantis shrimp can get to be over 10" long. they can break glass with a single swipe from their front claws. they will activiely hunt out and kill things in your tank. if you want one go for a species tank, as with bristle worm the Atlantic varaities will eat corals and other inverts as well as stinging you when you try to mess with thing near them.
 
Mantis shrimp will hunt and kill your inverts and smaller fish if they catch them. They are commonly known as EVIL CRITTERS so it is best to avoid them. Chances are that if you end up with one, he was a hitchhiker from some live rock. I have not had the unpleasant experience of dealing with one as yet but I do know that they can be very damaging to your environment. I watched a marine show on Discovery and they had a piece on mantis shrimp.....lil buggers are just plain MEAN.

mantis shrimp u definitly dont want they are highly effecient predators. there are 2 kinds the hammers and the spearers. the hammers have big thick claws that they use to smash clams, snails, crabs. the spearers are the ones that sneak up on fish and literally

the bristle worms are great scavageners in a tank. most people dont worry about the little ones. if you have a large one then you might want to remove it. but this is under argument right now also.

salty rick you have rock anemone listed. do you have someting else? because this is usually another name for aptasia. rock anem or glass anem. these are pest for the aquarium and can overtake a tank fairly quickly. also can sting your corals and kill them.

My Rock Anemone is not like the one pictured at your link. It is like the one pictured and sold on this site as "Rock Anemone". This site has it as as a "Epicystis crucifier". I have had it for two years and it has not multiplied or moved from its original spot. It is the only anemone that I have had that has lived for any legth of time.

I've bever got a mantuis, I wouldn't worry too much. Worms, I get. Never saw tyhe kind I get eatimg corals yho. Most are benign in my experience. Agaimn never saw a BW eating a coral, and I do look, lights on and off.
