GSP question

[Quill]

i understand that GSPs need snails and crustations. I wanted to buy him some snails but I was wondering, are there a certain breed of snail that I should get for him? or does it matter?

Any accept MTS
Malaysian Trumpet Snails AKA Cone snails
Anything that is the size of there eye I heard

Pond snails are considered nuisance snails and you can probably get them for free. You can also breed snails. like spongebob said though, stay away from MTS (look like icecream cones) because they can potentially break your puffers teeth.

EDIT: If you are interested in breeding them, I would recommend pond snails or ramshorn since they are easiest.

I would go for some Rams Horn or Mystery Snails. Plain pond snails as well.

Yep! If you want to have a specific type to search for, pond snails and ramshorn snails are common. You can also ask pet stores for pest snails, and they'll often give them to you for free. Just be sure to quarantine first!
