Boy or Girl Jag

[geno8701]

I have posted a few weeks ago with this same question. The replys that I got back were mixed 50/50. Today I have noticed some new behavior in my Jag, Is this a give away for the sexing of my Jag? Is it true that only females have the breeding tubes? Also she/he has become more aggresive towards tank mates. Has also dug out a little space. And has claimed one whole half of My 125 gal.



Here are the pics.

[MySpace Mike]

appears female to me. yes only females have the larger breeding tube to lay eggs. males only have a small pointed tube.

the thick ovipositor (breeding tube), belly full of eggs, and squared-off dorsal fin are what I based it on

Female, especially since its claimed half of the tank and is escavating for a nest.
