What do you all think it is?

Sorry no pic on it, I just happened to notice it on the back wall of my tank when the overheads were off. Looks like its about 1/8 1/16 inch long about 3/4 that in diameter. Translucent body, with at least 2 legs? tentacles towards its rear. I happened to see it moving along, looks like its cleaning the glass. Only reason I say its rear is cause u could see its body enlarge then it would move away from the leg thinggies. I know its not a lot to go on but other than adding gobie yesterday this is the 1st moving thing in tank except for the damsels. Dont know if its a medusa stage for anything as it seems too mobile but then again I'm no biologist. I did try and pics but they didn't turn out well. Also it moves at a good speed for something that small. Thanks

Sounds like it could be a flatworm.

ok got a couple of pics, they ain't the best in the world but here goes, plus hes eatin all sorts of little critters I just noticed on the glass, guess they're nocturnal huh? If a flatworm is that a good thing or bad?

Yeah..my 6 line wrasse used to eat them when i had some..

Cool tahnks, I don't have a reef so I guess I'm ok and as long as they clean things I can deal with them. I had just gone downstairs to watch the tank again whenI saw it on the close side of the tank, had to get the camera and got thoe pics. It's cool to watch all the little things alive in the tank now too.

Try this pic and see if it helps! This is what I used to identify the "white Flatworm" as was told that you probably have! After MUCH research, as Joshua said (where were you Joshua when I asked? :P ) they are harmless!

Not 100% sure though white ones are good but red ones are bad.

Red ones aren't harmful per se, but they're unsightly and multiply like crazy I siphon as many out every day as I can and they're still just as plentiful as ever. I hoped my sixline would help reduce their numbers but he doesn't seem to eat them at all.
