Is this a puffer?

[skeptik1]

I'm curious, is it even possible to keep a puffer in a small tank like 30g, or am I just being optimistic here? I'm guessing it's a no-go, but I'd love to hear your thoughts, experts.

A Valentini puffer could work in a 30g tank. It's generally reef-safe, but if it gets hungry, inverts and corals might become a snack.

I agree, consistent feeding is key to prevent your puffer from developing a taste for inverts. In their natural habitat, Canthigaster species tend to have a primarily herbivorous diet, although some larger species do consume small amounts of meaty foods like coflakes.
