Small opaque/white bugs on glass

[Todd2]

There is about 100 of these in my tank. They are small opaque/white and ovalish. They're not baby snails because they move too fast on the glass. The only new things I've added too my tank are the 2 bolivan rams that died. No plants nothing. I'm pretty sure there not snails also becuase they don't seem to have a shell or brown area on their body. Is this some sort of parasite that came in with the fish? They are about 1-2mm long also.

Any way you can post a photo for us to see?

Sounds a lot like free-living flatworms called Planaria. They are fairly common in tanks where there might be a build-up of uneaten food or other decomposing organic waste (like dead plants or lots of fish poop) in the substrate. Planaria are not parasitic...though they are certainly unsightly if you get a large population of them. Try a thorough gravel vacuuming to bring the population down to an un-noticeable level.

Thanks fruitbat, I think I might have a lot of dead plant stuff in the substrate because I had a lot of anachris die due to high temps. I'll gravel vac the tank soon. I have one more question are these things harmful to my fish or plants?
