i started getting some diatom algae in my goldfish tank .. and so i got 2 snails from petsmart .. one blue one gold ..
i put them in separate qt cups .. as i do with all new things i get (plants .. fish .. inverts etc) .. but they haven't moved in like 3 days ..
i've fed them each 5 pellets of goldfish food (since i thought they eat leftover food) but they haven't touched it .. and i change 80% of their cup water every day ..
did they die? @_@ .. how do i tell if they died ?
