My snail colony is off to a fine start after some donations and continual harvesting from my other tanks but I have this question - why do their shells start to turn white? Is it from being in cold water after tropical??
I thought that the little flat round snails were ramshorns, turns out they are pond snails. I got some round ramshorns that really are 'ramshorns' from a cold water tank, put them in with my other snails and they all died mysteriously over a few days, I don't know why. Now that some of the other snails shells are going white I wonder if I'm doing something wrong. Maybe they need their vegetables?
It's a plastic 20 ish litre container with a very cut down trickle of air stone bubble, some occasional food, no heater, no specific light apart from what comes in the window and some trimmings of aquarium plants from time to time. They all appear to be alive and possibly even growing otherwise.
