Sex of my Black belts?

[Andri Pogo]

I have 2 Black belts (Vieja Macilicauda), ~6-8" and was wondering what sex they were (if its possible to tell)

Didnt get them at the same time but at first they both showed similar colors.

This is the smaller one, both showed this color:

But a few days ago the bigger one changed color and i was wondering if this was a breeding thing or if its stressed? Doesnt look stressed in the tank though.

Here is the bigger one:

The 2nd one is in breed dress. When BB's are stressed its easy to tell, Their vertical barring is very distinct.

Wow man, These look like some quality BB's. They both appear to be males. The 1st one has his weight centered in the chest, usually means male. 2nd one has male fins.

My BB is still about 2in. Just starting to get the green sheen. Cant wait for him to get this size. I love Blackbelts

Those are some of the best quality BBs I've seen. Wish we had a good line here in the US.

He is a picture of a female in breeding dress I use to have, she was maybe 5" or so.

ok thanks, anyone else have gender comments on the first Black belt ?

If male, can two males get along fine ?
Would be nice to replace it for a female though.

I really don't know about the sex but they sure look better then my Blackbelt.

Color change could also mean that he is getting angry. When mine is being chased he turns dark, but when he is pissed off he gets very white/pale.

Congrats, those are real beauties. Do you know which ended up being the female?

Awesome! Blackbelts with fry would be very nice to watch.
