They're the rabbits of the aquarium world. That and pond snails haha
Haha, so I hear! I have yet to experience it first-hand though.
So far so good on these guys. I watched one trying to eat a little pellet food that got right in front of the filter intake. He was swimming hard, but was able to keep from being sucked up.
I added some Malaysian trumpet snails to all of my tanks yesterday. Hopefully they'll help with keeping some of the debris off the bottom
