Any experience on keeping Notopala Sp. new Guinea " Blueberry snail"?

[Sarpijk]

Hi guys I saw said species being sold for the first time. I could just find that it is a relatively new species in the hobby it also being described as a Viviparus Sp. Snail. What is very interesting to me is that they are live bearing snails.

Has anyone kept them? Would love to know that they do not as big as apple snails and do not harm healthy plants.
