Hi,
A while back, I got some info from someone about various snails. I have attached the information that was sent to me. There are some website URLs, too, with tons of information about snails.
Sorry about your plants
I think your yellow plant-eating snail is probably a
different variety from the true "mystery snail," aka
Pomacea bridgesii, which are noted for not eating
plants. link:
http://www.applesnail.net/content/species/...ea_bridgesi.htmI believe your yellow snail is probably the yellow
form of Pomacea canaliculata, which I have discovered
(through experience) are voracious plant eaters. They
are also a bit larger than C. bridgesii. link:
http://www.applesnail.net/content/species/...analiculata.htmI used to have 4 yellow C. canaliculata snails, but I
got tired of them eating the plants, so I traded them
at my local lfs. Now I keep C. bridgesii (mystery
snails,) brown ramshorn snails (about 1" high, I'm not
sure what species they are,) and small pond snails
(also unknown species.) These 3 species don't seem to
eat plants. But giant ramshorn snails (aka Columbian
ramshorns) definitely do eat plants. That's another
variety I traded at the lfs. ;-)
If I were to keep a plant-eating snail, I would want
to keep the largest variety. Pomacea maculata (aka
Pomacea gigas.) link:
http://www.applesnail.net/content/species/...ea_maculata.htmI haven't been able to find P. maculata for sale
anywhere, though. Whenever I find "giant apple
snails" or "apple snails" for sale, they always turn
out to be P. canaliculata. One way to tell the
difference is the color of the eggs. P. maculata has
green eggs, while P. canaliculata has bright pink
(almost red) eggs, and P. bridgesii (mystery snail)
has pink eggs.
