can planaria harm newly hatched corydoras

 

[Leedsboi86]

I could be wrong but aren't they an extra food source for fry?

 

[jonnyf84]

they wont harm them, i'm sure the fry would enjoy a nibble on them.

planaria are usually a result of over feeding.

Planaria are absolutely harmless and can be indicative of overfeeding. This is assuming that these are actually planaria and not one of many other white wormy creatures that can pop up unannounced.

Planaria have been known to feed on eggs but your fry should be fine.
