the snails are important mostly for their shells, the puffers crack them with their teeth, thus keeping their teeth (beaks) trimmed and in good shape. Without the snails (or something with a shell, such as ghost shrimp), the puffers teeth would continue to grow. If they are not provided with something to keep their teeth trimmed, they risk losing the ability to feed at all and shortly thereafter succumb to starvation.Originally posted by isaac newton
When puffers eat the snail they spit out the shell dont they? Arnt rotting shells bad for your aquarium?
I'm not sure about shells rotting badly in the tank, though I'm sure I've got plenty in the tank as my puffers have a nice continuous supply of their own snails to pick at. My parameters never seem to be off going haywired in one direction or the next.
