Help with sexing bristlenose. PIC INCLUDED


Recommended Posts

Just got this b/n was wondering if it was male or female it seems female as it is quite large and has little bristles but seems to have a ridge along the top of its head like a male.

Any help will be appreciated.

Hi Goliath

You will have to get a pic of its underbelly against the glass and post it up.


looking at the shape of the body I would guess at a male as females tend to be rounder at the belly and the males have more of a straight line down to the tale. HTH ;)

A male with not very big.......er bristles

Thankyou for the albino fry Holly :)

My vote is still female but, the photo seems to make the head thicker then it actually is and there are really not many signs of any bristles. Maybe we have a shemale ie thailand bristlenose :p

zilfin votes female too. The picture sort of makes you lean towards male but.

Its very hard to tell with this fish.

I just got a pair of commons of dobbin (cheers mate) and looking at the female he gave me it is a female.

Still never know.



hi, can I ask how long it is?

If there are any bristles along the centre of the head as in draw a line from the snout through the eyes it's male, otherwise most likely female, a good shot of the genital papillia will tell for sure :thumbup:

If you look at 1st pic

no bristles !!!

2nd pic all small and on the lower jaw

So female

AsYalost says bristles up nose to eyes = male

It is 10/12cm they say.

so should be at least a year old +

the uprased on the head you can see are the nose
