If you are speaking of Blue Rams Horn snails, then yes, they can reproduce on their own, or with a partner.
Wait they can asexually?!??
that explains why i only had 1 big rams and now rheres like 10
 
Ramshorn snails cannot reproduce on their own, even though they are hermaphroditic, they still need to copulate to reproduce

 
Ramshorn Snails are both hermaphrodites and sexual reproducers. This means they can either produce eggs all on their own or reproduce with a partner.”

 

Can Ramshorn Snail Mate Without A Partner?​


Despite being hermaphrodites, ramshorn snails choose to copulate before giving birth. This is one of their unique traits. Although they can auto-fertilize themselves by mixing their own sperms with egg cells, they choose not to. One major consequence of inbred breeding is unwanted mutation and other defects. One such defect is the situs inversus, which means that all the internal organs of the creature are mirrored. This results in problems like not finding a suitable mate.


But if snails prefer sexual reproduction, then how does a single snail sometimes multiply to many? The answer to this is sperm hoarding. Like some livebearers like mollies, these snails are sperm hoarders. In the wild, these snails don’t store sperm because they will easily find partners. But in captivity, when snails don’t find partners, they must either use the hoarded sperm of their own sperm for reproducing.
