A tiny snail (1/2 cm long)suddenly appeared in my plastic tub used for keeping hornwort & duckweed how could it appear? could there be a snail egg in the hornwort or duckweed and it hatched?

yeah, i get those alot! hey like to hitch hike on plants
i am too soft to kill them. if they are pest snails, you might like to take them out when yousee them coz they breed like wildfire!!
i just pt mine out in the garden

My brother purchased a plant for his tank and found a whole lot of snail eggs - so he put them in a tub and dumped them on my front door... said I could 'raise' them.... sadly, they didn't make it I thought they were big enough to put into a tank only my greedy goldie honed in on them and ate them...

I'm a bad snail keeper - that's for sure

hun, its not your fault we all make mistakes - unfortunately, its one i have made aswell

Jen,believe me when I say that you were probably better off with your Goldfish eating them.Chances are about 99.9% that they were either Ramshorn babies or the tiny little pest snails,and after having them for a short time,you'd be pulling your hair out because that's how fast they multiply!!! Listen to me....I know what I'm talkin about....Been there done that(Still doin it cause they won't go away)

Oh I think i'd put the snail in my goldfish tank see how my goldies like it
is 0.5 cm too big for goldies to eat?

NAW! I would think they'd be able to handle that!

I threw the snail out not sure bout the species and the shell already looks to hard for my goldies to chew so I just threw it in the garden
