What snail is this?




I found these snails in my tank and would like to know what they are. I'm assuming they're pond snails...which sucks. In the tank I have anubias var. nana, an amazon sword, microsword, and glosso on the way. Assuming these are pond snails are they going to go to town on my plants? I've read quite a bit about controlling snail populations, but was wondering if anybody had specific tips on removing these (assuming they are harmful to plants). So far I've been picking them out as I see them, or crushing them with the finger of god... I also have some MTS in the tank, as well as a couple of nerite snails, but would like to keep them.

Those are physid snails or also known as pond snails so yes you are right ^^ I like having them around but only because my puffer likes eating them I don't know how you can get rid of them without harming your others

they will not eat your plants, and wont multiply too much as long as you dont overfeed. If you've been controlling the MTS well, then you should have no problem

Pond snails will eat some species of plants. They just love Water Sprite. They soon will rise to pest purportions very quickly.

Thanks for the help guys! I've since read a little more about these guys and have come to the understanding that they don't eat live plants, rather they eat the dead/dying portions which leads most to believe that they're eating plants. I noticed some holes and chunks on my anubias and was about ready to order an army of assassin snails. I realized, though, that the anubias did have some yellowing/brown spots on them from being shipped, moved, and temporarily quarantined which leads me to believe that the "pond" snails just cleaned out the dead areas. Would love some more input on this, and if my understanding of what I've been reading is correct: that they're not a threat to my plants.

Afaik, physa acuta doesn't eat living plant matter, but will eat dead or dying parts of plants, and also eat algae and other forms of detritus which they find on plant leaves. They'll probably also be good for cleaning the glass.

Are both pics of the same snail? In the top pic it looks a lot different lol.

No, it's actually two different snails, are they the same species?

It doesn't look like it to me. Ive got physa acuta (the bottom one) and the top image doesn't seem to have speckles and the (spire?) is more to the side as opposed to at the back of the shell, it also looks less pointed.

I'm not really sure what is is, maybe some 'pond' snail native to america, probably be pretty hard to find out what its latin name actually is tbh.

Pond snails have a bit of variability in color... I think they're probably the same species. (remember, a poodle and a doberman are the same species. lol)


I concur, pong snails do not eat healthy plant tissue... If your plants are sickly and barely clinging to life, then they will be a nice salad bar for the snails. :)
