So I have 2 yellow rabbit snails and 2 lava snails, the yellow rabbit snails had a few babies almost immediately after I got them and when I got 2 lava snails a few months later I had all 4 in my 33 gallon tank. After maybe a month I decided to split them up so I moved 1 rabbit snail and 1 lava snail into my 20 gallon tank with my betta and a few Platy fish. This was probably 2-3 months ago. I noticed the other day that I have 2 new baby snails in my 33 gallon tank and it’s a little hard to tell what they are but they look like lava snails as they’re shell is dark and their skin is grey. I know that it’s pretty unlikely my lava snails would breed in captivity except in brackish water which none of my tanks are and is it even possible for them to have babies a few months after they’re separated? Yellow rabbit snails and lava snails won’t cross breed either I’m pretty sure. Anyone have any ideas??
