Anybody know what this thing is? It moves fairly quick. It almost looks triangle in shape (I have only saw it this one time.)
Terrible picture as the lights were out and I used a flashlight, sorry.

Thanks in advance.

Yes +1 ... I had a few of these in my tank, one big one still in there but took out some of the little babies, they don't seem to harm anything

They can have up to 6 legs I think, or at least that is the most I have seen. They procreate by splitting. Normally when all the legs are the same length, they are ready to split. They eat algae off rocks much like most snails. I have never had issues with them and they cover the back glass of my 120gal at night.

Neat! I kind of wondered if that's what it was but it seemed to be only half of it, I guess that's normal then.
Thanks for the replies.
