Apple Snails Dieing

[deanrar]

i have several apple snails in a shrimp tank and was wanting to put them in my community tank as there is more open space to see them, but when i tried 2 in my community tank they seem fine for a couple of days and then the next thing i know they are on their back hanginf out of their shell.
So i just wondered why could this be as the shrimp tank even has water from the community tank in it (the tank has 2 mollies, 3 dwarf gourami, 3 kuhlis and 4 cories)

Have you checked the water parameters?

Apple snails are sensitive to copper too. Do you use any plant fertilisers? Have you been using any medications that contain copper?

i will have the water parameters checked wen i next get to a fish shop and i have used some root boosta (I just looked at it and it contains extra iron doh!)in the last few weeks i didnt even consider that being a problem, but pest snails seem to do ok until i squish them and the fish eat them.
