I told my boyfriend to get the smallest one, but he didnt listen, It's around 1 year and half now, it's about 4cm long now. I knew it does grow really big, but we bought it for our snail problem, due to moving to a new flat, we had a temp tank for them without any snails or plants, and just move them to our new planted tank, it is 140L, but we put lots of substrates in there, we want to do aquascaping.
they are very playful. even tho they are not really in schools, and they are the bullies in the tank.
just normal snails, I've read somewhere that it will team up with other fish
