So my pet pufferfish transitioned today

I know lions are usually the example used to debunk the whole ‘being trans makes no biological sense’ agrument but please let me introduce another trans animal, the pea pufferfish

Bee here, (as pictured before transition) was female for the longest time. Females have white bellies. But one day I woke up and boom, bee had a black stripe down their belly, a sure sign of a Male fish.

Turns out pea puffers actually change sex depending on their social environment. In fact, they’re sexless when young and can develope into males, females and anything in between. Some even remain sexless.

I’ve only had bee for about three weeks. In the shop, bee was surrounded by other puffers. The ratio of males to females caused bee produce a lot of feminine hormone, and so bee became female at maturity. But bee lives alone in my tank now. And without others around him, he produced Male hormone and is now Male!!!!

Congrats little man 🎉🎉🎉🎉
