Can you tell what this is. Woke up one morning and there thay were. They are about 1/8 long, see-thru with a small brown spot in there middle. Also on one end they have two points. You can see one of them in the photo. Any help would be great. It looked like it was eating off the glass. Here it was moving into a rock. View attachment 37771 View attachment 37772

Looks like a flatworm.

A few choices.
  • You can leave them. They aren't bad until they reach epidemic proportions (based on water quality) and start smoothering the corals of light and reducing respiration.
  • Nuke them with salifert flatworm exit (carefully).
  • The Berghia nudibranch specifically dines on them.
  • Or you can test your luck with a six-line wrasse or a dragonnette.

Isn't the Velvet Nudibrach the one that eats flatworms and the Berghi eats Aptasia?

odd, Safari does not view them correctly, but Firefox does.

anywho. i am guessing you have gotten new LR in the past 2 weeks. those are a type of flatworm. they are also known to eat the plague flatworms. most of the time they starve rather quickly in the systems. if you know somebody who has a flatworm problem give them to them and let them have at the flatworms.
