i have a 10g tank and I'm hoping to get a puffer or two. I know that they need to eat snail to keep their beak size down so i am starting a snail colony in an old 1g. I got free snails from the pet store randomly, they look like MTS and ramshorns. how do i breed them fairly quickly. I put some carrot in there and they don't have a heater, only a small hob filter
