Hi,

Are these things harmful to cherry shrimp and will they multiply fast? I have removed a few but many still see more.
One over 1 inch length. Has round mouth that anchors itself to the walls but are found in the substrate peaking it’s nasty head up. They are red pink like earth worms, does not look like planaria.

I also have snail infestation which I removed most but still see tiny baby snails. It is a 2.7 gallon tank. If I remove
the substrate and soak in vinegar, that will kill all the snails? How about the plants?

Thanks

Looks like a leech.

Definitely, a leech.

Ugh... Thanks.

I read the eggs are next to impossible to destroy. To toss out all substrate.
