clear flat worm good or bad?

I found a clear flat worm in my refugium.He looks cool.He has a sail he blows up to move.He looks like a circle with a v in the back.I found a pic of him online and they said he was harmless but on another site they said flate worms are evil...
I also have tiny clear shimp,copeds and red brissle worms.I just want to know if i should pick them out before they spread into my tank.
Thanks for checking out my post and any advice would be great

 

Welcome to 3reef, the flatworm is the only one I wold worry about they cause problems if their numbers get too high by suffocating your coral. Bristle worms are clean up crew members and good almost all of the time. The copepods and shrimp like animals are good as they can also be part of your CUC and food for your fish.

 

So i should pull them out?

 

Welcome to 3reef.

You can find your FW here, based on your description it is indeed one of the harmless ones. There are many many different types of FW some are a major pain, your is not.

There are other FW that look very similar so make sure your ID is correct. At the end of the link below you will find the FWs.

The decision is yours based on what the information you read makes you feel about them.

 

Wow this site is crazy good.On the link the worm i have is the clear flat worm amphiscolops.It said it is a score and not bad.They do eat copeds but my refugium if full of them and it has only been running 3 months.

Will the little clear shrimp grow up or do they stay small?

I am starting to think i need to put my refugium above my tank so i dont have scrambled shimp getting pumped into my tank.Right now i have it draining into my wet dry filter so theres a wild ride to the main tank.
Thanks for all the help

The little shrimp will most likely get no larger and your pump won't do much if any damage to the pods.

 

ok thanks for the help i guess they can live if they are not bad.I think there cool they look like aliens.its sooo cool when you find new life in the tank

 

What you'll notice is that the Amphiscolops population will begin to wane as their available food source (copepods) disappears. Being predatory, they will only populate the tank up to the level it will support.

I think these are super cool flatworms, and have literally sat and watched them for awhile every so often. In the photo on our website, you can see it pursuing a small reddish pod, and if you look at the worm's gut, you'll see several already being digested.
