I just got some pea puffers after not having kept them in like 10 years! I never got to know them because mine died after like a day. I did not know how to care for them at the time.
I always assumed that no matter how aggressive they get, they cannot be taken seriously because if their size and you would just laugh like you would at a kitten. Well, no that is not true. They are terrifying hunters.
