Hi, the snails just die... still inside the shell.... khulis never touched them and they were too big for the dwarfs...I added them when I realised just how prolifically the ramshorns reproduced and hoped to slow them down by having the babies eaten...(that problem is gone though hahaha....
Now though, I have no loaches at all and the snails died overnight.....
Although it was only a 30% water change it was a total substrate change...so at first I presumed it was all too fresh for them... but now after about three months the tank has recycled but I still get the same result with the snails.... they only lasted...hmmm well I'm not even sure if they lasted the night... I put them in the tank one night and the next day after work, dead..... I just have no answer for it.....
Other fish include sterbis(?) corys, albino corys, neons and serpae tetras....actually this is all that is in there now....loaches are all gone.
I spose I should add that the tank had been running for about 14-15 months prior to my substrate change with no issues.....Infact it must have been great as the reproduction of the snails was amazing.
