Worms in my tank

[TO KYO]

When over feeding your tank you might start seeing some small tiny worms swimming around your tank. I was told they are harmless, but what if my mollies eat them?

I forgot what they are called....I believe that they would be harmless if fish ate them. In extreme cases, the worms can latch onto the scales of fish.

While the worms themselves can be harmless, the presence of these worms is likely due to poor water quality such as extremely high nitrates.

A little disclaimer here, I wrote this without doing any research. I believe what I have written is accurate. My water quality has not suffered in a long time. Worms are not something I've experienced.

@Metalhead88 is correct and they are suppose to be harmless but I would do a major vacuuming and water change

Planarian or aquatic worms are not dangerous to fishes but for shrimp it is, last time they killed my amano shrimps.
