Ramshorns are considered pests, because they multiply so quickly. They are a dime a dozen.

They are used as food for rays and puffers. The guy I knew with a ray has sold his (I emailed him).

I was told I can put them in a baggie and use a hammer to smush them up, makes a high protein fish food. I just couldn't do that.

Since I had to go to bed, I finally put them all back in the tank.
