Well some interesting stories.
I think some people on this site no alot & some no nothing, thats why i like this site..........lol........i have been breeding different types of fish, cold & tropical for 25 years & still have lots to learn.
Also breed Turtles, Red Eared Sliders & Blue heelers/dogs.
Have done some of my own looking around & asking a few questions.
And this is what i have found out, for anyone that is interested.
They dont need to come out of the water to breath, they can live very happily with out leaving the water, they have a long tube that comes to the surface that they take air in through, but thats not to say they dont come out of the water to breath aswell.
From what i gather they need to pair up to breed, cant do it by them selves.
They lay there eggs out of the water so the fish or other critters dont eat them, when the hatch they drop into the water.
They also like to go walk about, the chap i spoke to has had them for 30 years & sometimes he finds them all over his garage floor in the morning, they like to get around.
They are part of the Apple Snail family & can grow very large, not as big as the yellow Apple Snail, but big, tennis ball size, so looking forward to that.
They can devastate a planted tank in days, so not much good if ya like a planted tank, wont last long with these suckers.
They can live for up to 25 to 30 years if they are in the right environment, they also need calcium to stop there shells from going soft or pitting out, just like Turtles, same sort of thing.
If you feed them heaps they grow very fast.
Thanks to those people who had something to add.
Cheers
