6 Gallon Tall Fluval w/ Pea Puffers?

[day5792]

I've had my 6 gallon for a while now, and I want to change things up. It's currently half RO and half fresh water, with one viper shrimp and one ghost shrimp. I also had two pygmy cory catfish, but I moved them into a larger 30 gallon community tank. I also have a large community of nuisance snails in there in case I ever decided to use them for feeding. So that brings me to this question; would this tank be suitable to have a few pea puffers? I'm concerned that they may try to eat my shrimp, but if they did start to harm them, I do have a back up tank that I could place them in. Aside from the shrimp, could I have a few pea puffers with half RO and half fresh water, or should I just have 100% RO? Also, would I need to keep some snails in a separate aquarium in order to breed? Any information would be helpful, thanks!

The 30 gallon is suitable for a puffer, maybe two with bullying. The 6 gallon is suitable for a betta.

It is likely a puffer will try to find out if the shrimp are edible.
Aside from the shrimp, could I have a few pea puffers with half RO and half fresh water, or should I just have 100% RO?
RO water is typically used by marine enthusiasts and freshwater enthusiasts without reliable tap water. Is your tap water polluted? Why do you use RO water?
Also, would I need to keep some snails in a separate aquarium in order to breed?
No, a puffer will not drive your snails to extinction. If it were only that easy...
Any information would be helpful, thanks!
