White Slug Like Creatures All Over My Glass!

[RobGoldsmith]

This morning i looked at the glass and there were a collection of empty brown sacks or eggs along the glas, possibly 20.

I looked closer and there were little slug like animals moving fairly fast along the glass, they were around 1mm long and white. They also didnt slide along but get short and long over and over! I cant focus to take a photo but some of the fish were having a nip.

Any ideas?

Thanks

Rob

Planaria worms? Is this a new tank?

5 months old tank, they looked like ovals stretching long and then more round, they were definitely moving along the glass and very slowly stretching back and forth. Might that be them?

Googled it, looks like them! what do i do?

I had something like that once they attached themselves to the snails!! presumably sum sort of parasite I found lots of them in the gravel!
