i think i just need to give up
ive been trying to grow snails in bottles and i got at least 20 snails (all types) mostly common pond snail
and all of them are dead
the only thing i can think of that killed them are metals that i seem to have in my tap....
i also tryed rainwater bc of that ...
now there are just 2 that are barely alive and they have climed out of the water and are not moving
Snails do best in filtered water, just like fish.
In your situation, I would consider buying a breeding trap, hanging it in the tank, and putting some snails in. It might drive the puffer a bit cuckoo trying to eat the ones he could see though, so I'd get a plastic one rather than a net one.
