Snail ID Please

[Joetee]

I suddenly found a few snails in my tank. I have been looking online for most of the day to try and identify these but I am having trouble.
I thought they were Olive Nerite but now I am not sure. They look like them a bit but they have a swirl that points to the rear not the side, maybe two or three swirls. They do not have a door. I don't see any antenna's. I don't think they are Trumpet's because the swirls are not that long. They also don't seem to need to go up for air so I suppose they are aquatic snails. They are not like a round ball, they are longer than wide.
They are a dark color kind of like the Olive Nerite.

They don't seem to be eating any plants but are going crazy on the algae. I first seen one, and now about two weeks later, there are maybe 4 or more with some tinny babies.
I did a google search for photo's but they don't really look like anything that I have seen.

Can anybody point me to a good site with good photo's or maybe a name?

I received plants from two sources so I can't say from where they came from.

So far, I don't see any harm in them.

Thank you

Joe

pachyomelia spp? Malasian livebearers maybe. Are you sure they don't have a trapdoor? Most species like that do have a trap

No (traditional) antennae, a small number of whorls, football shaped(longer than wide).

Malaysian trumpets are quite pointy, they're really quite conical. Very distinct at any age and size.

Thanks everyone for all your help. I was wrong about the antenna. They do show 1 pair of antenna.
I will check out all the links you all sent me now.
Thank you

if it looks like this its a pond snail

[Joetee]

Sorry it took me so long to get back to this,
I think the type of snail I have is Physa sp.
Reproduce like mad.

Question: Do these snails cause any trouble for Red Cherry Shrimp?

Thanks
Joe

That's how my fascination with snails started, by studying the little guys who hitchhiked on the plants.
