How can one tell the difference between a male and female pufferfish?

Answer 1

Female guppies are much larger and less colourfull. They also have a triangular anal fin. The male is a slim very colourfull fish and has a pointed anal fin which is called a "gonopodium" and this fin does a similar job to a mammals penis.

Answer 2

Female guppies have a black spot near their belly area for live berth. Male guppies have a transparent grey fin near their belly area. Hope I helped!!

Answer 3

You can't tell the difference, unless you see her laying eggs. The birds' colors are the same regardless of gender.

Answer 4

The male pufferfish has a penis and a female pufferfish has a vagina
