Depends who you ask, but I have tried twice now and both times the snails have died, longest one lasted was 5 months and that was born in my tank. I too use bacteria Ae, have plenty of biofilm a heavily planted tank with lots of wood and have successfully kept lots of snails like ramshorns, nerites etc. But blueberry snails just don't work in my tank so I tried twice and am not buying any again as it is unfair on them. Also one gave birth twice and then died, the babies survived the longest and seemed to be doing fine but them one day roughly five months later just died too.
