Outdoor Pond Snails

What snails would survive the Gauteng winter in an outdoor pond?

 

Well it would depend how cold your pond is in winter and how well it’s insulated. As far as I know (I could be wrong but its what I found through research when I kept them) apple snails can be kept in temperatures from 18-28*C. If your pond is warm enough for the snails just remember to acclimate them very slowly as they have been kept in warmer waters. I would suggest keeping them in a tank and slowly dropping their temp over a few days to prepare them especially it they’ve been kept in very warm waters.
Maybe someone else could give better advice but this is what I found from research.

Seems like 10 degrees celcius is where the limits are.

 

Hi all, I'm quite new to the forum but thought i'd contribute. I have a swimming pool that's sitting at around 11-12 degrees Celsius and I have a ton of pond snails (Physella acuta) that seem healthy and happy, and quite big actually.

 

Physid snails - like Physa and Physella mentioned above - are quite tolerant, especially considering that there are local species that no doubt have made their way into our aquariums as pests.

In any case, this is risky practice. Snails can be major invasives, and in wet enough conditions can travel between water sources very easily. Not to mention other pathways, like hitchhiking on water birds or getting flushed with wastewater. Many species of snail (especially Physids) don't need a partner for fertilization, so it only takes one...

Just consider it.

 

Oh jeesh, they just kind of appeared 0.0 I guess that's why
