The Puffer Forum

Hello all..just was wondering if anyone has any true info on how to determine what.sex my fish is...thanks all for any info

As far as I know there isn't a way to tell the difference.

From what I've seen you can't determine the sex with ou t have a test done

Flip a coin. Heads for male and tails for female lol.

Puffers in general seem difficult to sex. What are the easiest puffers to determine I wonder?

Probably dwarf puffers, since they have "wrinkles" around their eyes if they're a boy.

How? Pick the one you wanted in the first place!

Carinotetraodons are easiest to determine. They all have differences between the sexes.

once they mature you can tell by if they drop eggs all over the place(with fahaka's at least)

Do the females do that automatically, or only under certain conditions?

Actually only under certain conditions do they fill with eggs and drop them. Those are of course the usual limiting factors in puffer health and lifespan:

1) properly sized and equipped tank
2) proper feeding
3) proper and consistent maintenance.
4) freedom from disease and stress

So it is only four things to watch out for...

Ah okay, thanks! So as long as the puffer is happy, healthy, and well-cared for, it should be normal behavior.
