Red nudibranch

Recently I have had an explosion of what I believe to be red nudibranches. Is there a difference between a sea slug an nudibranch. My concern is are they dangerous to my reef? Research on these animals are very difficult.
Unfortunately I cannot get a picture. They are just too small.

 

Do a google search for red planaria and let us know if that's what you've got.

 

I don't believe it is a red planaria. They look more like slugs and are very bright red. Any other thoughts?

 

As amcarring suggested, it sure sounds like flatworms to me.

Try to syphon some out and place in a white bowl and get an image.

 

Will do. They are very small. A picture will be difficult. If they are red planaria, are they an issue to my corals? Do I need to be concerned?

 

Yes they can become an issue because of population explosions. And treatment is somewhat involved, not too bad but needs to be researched and done carefully.

 

If you have flatworms, they will be almost as wide as they are long. If they are four or five times as long as they are wide, they might actually be a small species of nudibranch that feeds on spirorbids, Vayssierea felis:

I am not convinced I have red planaria. The creature in question looks more like the site pagojoe posted, only all red. I'm leaning toward a sea slug. Unfortunately I cannot get a good picture.

 

Do they look anything like the spots on these zoas? If so I've been told these are flatworms and I will have to treat my tank with flatworm exit.
