Alien Organisms In Oscar Tank

[TigerOscar]

I have an Oscar tank, and the ecosystem has been exceptional for its whole life. I found a rock at a local lake, it was dry and had been in the sun. I figured UV rays would have sterilized it over time. So I brought it home and dropped it in the tank.

Five days later, really small and stubby white worms are all over the walls of the aquarium (also really bad algae problems). I think eggs had dehydrated on the stone then hatched when I dropped it in a life sustaining water source.

Now, what the heck do I do? I don't know what these things are, if they're dangerous to my Oscar, or how to get rid of them.

Does anyone know what to do?

(I also know for a fact this isn't planaria, I've had it in a previous aquarium before).

Well, first you learn a lesson: clean everything before adding it to the tank.

Secondly, can you post a photo?

I had some "worm" like creatures in my tank - amongst the gravel on the filtr sometimes wriggling down in the water, sometimes on the glass. Under the stones (you could see it through the glass) they were in the earlier development - larvae stage. My harlequins were eating them if some fell down from the filtr. After that I was feeding less - no food on the ground and they died out. I don´t know what they were...When I took one out it looked pink. I know now they came frome the root I bought in pet shop
- the next time I bought new root I poured boiling water all over and small dead white thin warms were seen in the water. No more worms appeared.
