View Full Version : What kind of snails are these?

I found these two little guys on my tank today - above the waterline. Can anyone help identify them - and are they good or bad for a planted aquarium?

(obviously plant hitchikers as I haven't purchased any snails)

Common Pond Snails. I have a few of them as well. Not necessarily bad hitchikers. They won't harm your plants, just watch them close, they will take over in a hurry.

Thanks for the quick reply!

It's hard to tell for certain from the pic, but they look like some I have in my 30. If they are the same species they won't grow any larger than they are now, and are plant-safe from what I can tell. The tank no longer contains live plants, but while it did they weren't being eaten by snails.

they could be of the physa or radix species, it depends on their tentacles. If they are long and thin you have a physa, if the are short and triangular, you have a radix. Both do no harm to your plants, but they like to explore the surroundings of yout tank. If you don't find them quick enough, the'll die.
