Red Flatworms

[OrionN]

Mihn, What are those fleshy colored flatworms called?

Misti,
I am not sure of the species but they are of the same Genus. The red ones are free living and do not bother corals. The pail color one pictured here are parasites of solf corals and LPS.

Very interesting pics Minh...So you should know if you have these guys...they seem to be pretty noticable. On the red fleshy ones...can you actually see them moving?

Sherri, they are most active at night and you can easily see them moving in the early morning, just as the sun comes up or lights come on.

I have gone the natural method since they don't hurt anything and are hardly noticable anyway. They seem to eventually dissappear. Things are doing well, so I am not adding toxins to the tank anymore. Less intervention. I gotta agree with that. The less I add of things other than a few trace elements, the better it seems to work out.

The pale color ones are dificult to see, unless you have lots of them and/or looking for them specifically. I got about 100 of them on my Alveopora but did not see it untill I look at the picture above. I was taking a close up picture of my coral. Looking at the picture, I find out that I got flat worm.

I saw mine on one of my frags, like I said at the begining. They were flat and some of them were kind of floating their foot, almost looked like it was plating coraline algae, until one of them was startled be something and caused it to move. Very hard to see because they blend in with the reds and purples of the coraline.

Well...took a good look and don't see anything...but now I know what to look for. They are usually brought in on new LR or corals then?

I think mine came in on either coral or LS. Most likely LS.
