A few things...ID?

depending on the size of your tank, i cant think off the top of my head but i know some wrasses will eat them, might be some other fish that eat them as well... or a product called "Flatworm Exit". being ive never had flatworms ive never had to use this product but ive allways heard "be carefull when you pull the trigger" not sure what that means but hope this helps ;D

 

Red planaria don't destroy corals and/or other inverts. They can harm corals passively by covering corals thereby blocking the light from reaching the coral but they don't eat them. I would go the Flatworm Exit route myself but that choice is yours

 

are you saying there algea eaters? everyones allways told me they prey on coral tissue...is that wrong?

 

I've never actually seen them on any of my mushrooms, frogspawn, sun coral, gorgonia, or feather duster. they only seemed to like the tunicates. Other than that they're mostly on the glass and to a lesser extent on the live rock.

I think I will try and suck a bunch up when I do my next water change. Once a week should keep their numbers low at least. I'll mention it when I drop by the LFS.

Thanks for everyone's input thus far!

 

If you haven't seen them on your livestock, it's because their numbers aren't great enough yet. For every one you see, there are probably 50 you don't. Sucking them out manually is not going to make any substantial difference in their population.

What's been said about Flatworm eXit above is correct. It works. Since this product kills them fast, and since their numbers multiply fast, it's a prudent action to hit them ASAP.

Here's a thread about Flatworm eXit.

Good luck!

 

There are some flatworms that eat corals but red planaria eats algae and detritus.

 

I will try to get to the LFS and see what they have to take care of it. For the time being I've just suctioned a bunch of them out. I'm debating on whether or not to throw my yellow-tailed damsel in there. Someone mentioned he'd help get the numbers down. A bit hesistant though because I may never get him out again without destroying the set-up, haha.
