no. kill those ones you find crawling cause they are probably pond snails. they wil form bubble nests and reproduce very, very quickly and will overrun your tank if you do not detsroy them and their nests.
buy a loach, yo-yo would be great. a yo-yo specializes in snail killing.
next, watch your filter very very closely. they will migrate to it and form their nests inside the housing, along the walls where there isnt too much turbulence. i learned this the hard way. they reproduced so quickly when i had a 10 gallon tank running that no matter how many i took using my hand off the leaves and rocks, they would come back stronger than ever. after they literally devoured my plants ( 1 anibia on lava rock, 2 swords) one night, i tore the whole system down. i found they were inside my filter, which was starting to have all sorts of problems in the impeller well. when i removed the impeller, there was a whole pool of snails shells that were grating upon the machine. plus, the nests were all over the inside of the filter, with the culprits nearby. they were even eating the bacteria upon the bio-wheel.
i tried the lettuce method and picking them by hand- they are band-aid solutions, which to me are fruitless wastes of time. they do not remove the root of the problem, they just trim it down. similar to those wretched dandelions that lawn caretakers despise, you have to remove the root and not just the yellow flower so that the thing will not come back. in this case you must remove the root, the nests to terminate the infestation.
so, before they become a bigger problem, buy the loach/es and then start keeping a close eye upon your filter housing. that has been my experience. in fact, right now i am battling pond snails. this time though they have to over come my cleaning of the filter housing every 3-4 weeks, the clown loach, and the ram cichlid i keep. the dwarf cihclid, a male bolivian ram, does eat snails, but not with asuch vigor and as a large an appetite as the loach. between those conditions, they are visrtually non-existent except for the few inside the aquaclear filter in the area between the psonge and the clay cyclinders. they form their nests there.
sorry for the long post, but i do not care for pond snails nor do i have some weird fetish for them as some people do- i see that they have their place in nature, but not in my controlled set-up. good luck
