Hi, i just got two pea puffers for my 5 gallon aquarium since the person there recommended that i get two so they wont get stressed. Is it ok to keep two pea puffers in a 5 gal? my tank is quite densely planted btw.
You certainly can. It might be better to have 6 or 8, in order to spread around any aggression. They aren't safe with any other kinds of fish, though. They are notorious fin nippers. Besides snails, mine liked newly hatched live brine shrimp and frozen food, especially bloodworms. Puffers have lots of personality, one of my favourite fish.
