Our fish tank is overloaded with Ramshorn snails. They came in on some of the plants and procreate easily. So now I have a snail nursery in a small fishbowl next to our big fish tank.
There’s a rock and a plant in the tank and I feed them lettuce leaves which they devour.
This is a video of one of the baby Ramshorn snails walking on the root of the plant floating in the tank. The snail is less than a quarter-inch long, and still so elegant.
