oh well neither snails need both genders to breed XD
do I need to feed them?
yep you need to feed them or they will die just like any other animal
Yep you need to feed them. *sometimes* they can just live off algae if you have a lot. But it's a lot easier to drop a vegetable in every so often
I feed mine cheap koi pellets (what I feed my crickets). You could get a sterilite tote with a simple filter (I have a bottle filter, but filters aren't necessary, they just breed faster for me with a filter and overfeeding). Bladder snails breed faster at a lower temp than ramshorns IME, so I would recommend bladder snails unless you have a spare heater. Overfeeding a bit when you have a filter speeds up breeding. I also put mine in direct sunlight to grow algae for them. All these snails really need is a bowl, but improving the set up speed up the breeding a bit.

I’ve had 2 generations of snails grow in my jar living off of biofilm.
