flatworms?

[hammcd]

I decided to make a new thread instead of using my other ID thread...i know these are flatworms...i found these today in my 30gallon tank which has been cycling for about 3-4 months now...all that is in the tank is rock, sand, a few zoanthids, snails, an emerald crab and a scarlet hermit...
i was just about to put fish in there this next week but now i am kinda scared...
someone said these types of flatworms are good..or at least not the bad variety because they arent brown...in the pic they appear white and they are the size of a pinhead...on the glass here they are white on the outside and kinda darker..maybe brown in the center...is it possible these are the bad kinda but just babys...
do i treat for flatworms no matter what type they are..ive heard horror stories from treating and the toxins they release...i guess it is good that i dont have much in the tank at the moment...but if they are a good variety id rather not risk treating them....any and all opinions and experience is welcomed
thanks

I had the bad variety of red/brown flatworms in my QT. I used Salifert Flatworm exit and it worked like a charm. Key is, after the flatworms dead (about 20 minutes or less, you watch them start to quickly spaz out and die) I did a 50% WC and ran carbon. That was a couple weeks ago and all corals and fish were fine. I think the massive WC is the key.
I'm no expert though. Just my experience.

Those are flatworms. That kind is harmless thought. They are vegetarians and eating the film algae on our glass check http://www.melevsreef.com/id/clear_flatworm.html">this</a> out and see if you agree. I had the when I started my tank and freaked out too. They will just be fish food.
Good Luck!

Those flatworms should be harmless. However, they do reproduce fairly rapidly. Since you have such a small system, if it were me, I'd probably treat for them, especially since you don't have much in the tank yet. Do the massive water change as mentioned above, as well.

If you had a larger system, and a sump, I'd be recommending you leave them and get a fish that eats them to keep them under control in your display. Then you have a good source of food for the fish, and an added member to your clean up crew.

are there any fish that might fit in a 30gallon that would eat them?

Clear FW are slow reproducers. I've had them for a year now and see just as many as when I started. They have a split tail and a small dark colored dot in the middle. I did some research and everything I read said they were productive for the ecosystem.
