hi everyone..does anyone know a way to get rid of bristleworms? i just lost a large deresa clam which i had for almost 2 years..ive pulled them out with a tweezer from the clam and the next day i see more until my clam died..i dont over feed, just 1 cube every other day...i do a 10 gallon water change every week/2weeks to syphon my gravel but still i see alot of bristleworms crawling out when i feed my suncoral..i do want to buy another clam but i do need to find a way to protect it...any advise would be helpful.

The bristleworm didnt kill your clam. He was just doing his job of cleaning up dead or decaying tissue from either the clam being unhealthy and dying anyway, or from another predator such as a polyclad flatworm or pyramidellidae snails.

Bristeworms are your friend and part of your clean up crew. If you have a ton of them then you have excess nutrients allowing them to thrive.

Yes they are much smaller then bristle worms and I agree with them!Sorry for youe loss.If you have to many bristle worms they still won't kill your clam but you can buy Exit from Salifert to get rid of them,but there good for the tank.

A six line wrasse will feed on bristleworms, and is a very beautiful fish. I would get a trap for the bigger ones. Bristle worms get a bad rap because most are scavengers, and are found on dead fish. There are a few that do hunt, but chances are you just have the scavenger type. Arrow crabs also do a nice job of cleaning them up if populations get out of control. <!-- / message --><!-- sig --> <!-- / message --> <!-- sig -->

Polyclad flatworms are typically 1" to over 5" long and a 1/2 their length across. 3.5-4 inchers are very common of the ones that are found

Out of the main system experimenting i have tried to kill them with FWE and it doesnt even phase them until you get to a 40x or more dosage which besides costing a ton of money I dont think would be a good idea in your display

here is one of the ones I have had over 4"

Here is a stupid question Geoff. Can pyramid snails live in a tank without a clam? I've never been into clams, but am thinking about one for my tank now... I often see little snails, but never was concerned about them until now. Next time I see one, I'm going to pull it out and see if it's just a baby cereith or something or a pyramid. But since I changed out everything recently, it could be months before I see any again.

there seem to be a bit of confusion out there on pyramid snails. there are either two different species or one species that can feed on two different hosts. most people believe that there are two different species that require their own specific host.

ok, now for the explaination for the above statement. :D pyramid snails will need to be introduced by its host. either a clam or Astrea snails. they can not feed on any ol snail. they seem to only feed on Astrea snails. those that feed on clams seem to be able to feed on any Tridacna clam. i have not heard of any feeding on Hippopus clams, but then again these are fairly uncommon in the trade. certain clams seem more susceptible to pyramid snails, those being crocea and maximas. it may have to do with size though. i had a decent infestation several years ago and my 8" squammie did not seem affected by them at all, while my smaller croceas and maximas had to be cleaned quite frequently to keep them healthy.

pyramid snails are bright white in colour and less than a 1/4" in length. Ceriths will be bigger and have colour to their shells even when young. Ceriths also have a rounded opening while the pyramids are more sharply defined and squared off.

if you have Astreas, you can see the tiny pyramid snails hanging out on the underside of the Astreas when they crawl along the glass. pyramid snails will be attached to their hosts. this is why it is a good idea to have a look at the undersides of all clams when you buy them. maximas and squammies are the most difficult to look for these snails because of all of their scutes.

Thanks Geoff. I usually research things till I'm blue before I buy them after having a few nightmares in the past. So I'm just now touching on researching the clams:) Maybe in six months I'll actually buy one.

I'll look at the few astreas I have left and see if I have any hosting. My snail population dwindled significantly moving to the new tank.

hmm, that hole was not done by the bristle worms. i can not remember which predator drills holes in clams, but that is your culprit. i will see if i can hunt it down for you, but hopefully someone else will remember before i can find it.

i have found something. for some reason i was thinking it was a snail that drilled through the side of the clam, but this site has a worm listed. it is listed under the Oenonidae (Clam Worm).

i would do another search for these kind of worms and see if you can find more info.

HTH,
