Its hard to say for sure, but they look like they might be planaria to me.
If they are planaria, then you have no problem except maybe a little extra waste food in your gravel.
Keeping the gravel clean (vacumming and reducing the amount you feed) will pretty much take care of them. Also, many fish will eat planaria.
Thanks for the reply jim I didn't see your post until after I made the above reply. If they're Planaria then great but they sure don't look like the pictures that I'm seeing So far. Everthing in the tank appears to be in good health except the Danios are on a bit of a hunger and activity strike.
The P. Alternans are closest to the worms and appear to be doing great.
Heres some shots I took last night. Any excuse for some fish pictures, right
These guys are racing up and down the tank now daily.
Our male Ancistrus is proud of his new whiskers (to early to tell but his? tankmate is the same age and shows no whiskers, Late bloomer?).

And even prouder of his big stickers.
Mr. Smithi likes wood.
Mr. Smithi is very upset that I allowed a piece of gaudy blue gravel in his tank. Bleh
