Green Spotted Puffer Fish

[buhner_7]

Does ANYBODY know how to tell male from female Green spotted puffers? I cant find it online anywhere. I would really like to breed them if possible. They are the greatest fish ever

it is impossible to tell the sex of the GSP I'm afraid.. at least while it's alive as they are sexed internally.. people have been researching this currently to try and determin a behavioural distance but results are still quite a way off in the future... what I can tell you though is that if you are lucky enough to get males and females obviously the female will lay the eggs but the male always moves them to a cave or hole in the substrate and tends them and guards them.. this is the only info available on the subject.. sorry.

tyvm bulldog118 one thing i have noticed with my 2 are that the bigger one is a little bit more aggressive, and the smaller one always fallows the bigger one around. i was thinking it MIGHT have to do with the sex but im not sure? Might just be dominance prolly.
