LARGE flatform??... found... in 29 gallon tank!

[Reef55]

Ok, so going to bed with the lights off in the tank I took a quick look and found this thing taking a stroll near the front glass. Very flat, two little eye things that stick up at the front in the direction it moves... if it free floats it balls up with wavy edges, but as soon as it touches something it flattens out again. Anyone with an idea of what it might be (besides flatworm... )

Thanks,
Mark

polyclad flatworm, that one may be carnivorous eating snails.

Yup, it's a polyclad flatworm. A specialist would have to examine it to determine what genus and species it is. All flatworms are carnivores, eating snails, clams, tunicates, small crustaceans, worms, etc. Read this article by Ron Shimek to get more information:
