Found these in my sump. I collected some by just dipping a glass in the sump and looking at it, they stuck to the sides pretty good and swam pretty fast. Hope they are not flatworms??

It is a flatworm but not the type that feeds on corals. The eat biofilm and are pretty harmless. Some people have problems with them if their populations get too large but keeping water quality very good will stop that from happening.

Ok thanks guys....our UV bulb went out and we started getting cyano in the sump...maybe that's what did it. Should I try to get them out? I haven't seen any in the DT.

You can siphon them out if you want but they wont hurt anything

How do you tell the harmless flat worms from the bad? The color?

Generally, I determine it by where I find them. If they are crawling around on corals, then I doubt they're good. If they are just on the glass, then they are probably harmless. Typically in aquaria, the little white/cream ones are fine, the little brown ones are potentially bad and the big ones are probably carnivorous.

and the red ones aren't too good either!
