PostSubject: How and what age can you sex ?   Thu Mar 04, 2010 9:25 pm

Hello all - as per the subject - at what age / size can you start to sex your Bristlenoses and what should I be looking for in terms of a female or a male ?

What kind of growth rate should I be looking at as well from a jouvenile ? I think this would be a useful addition to the site as part of a breeding FAQ. I'm planning on starting a regular thread to monitor the growth of my L144 pictorally - I've measured each of the favourite spots so whilst not a very accurate guide I should be able to get a less subjective view of growth as I know how big they are - and hence how big he or she is. I'm picking up a new SLR next week - so at least this time round the images will be in focus.

You might be able to sex from 2 inch by looking at the head and mouth
However sometime both male and female L144 grow bristles
The male will have bristles up it's nose and head and the female if any will only be around the lips / mouth

sounds good cannot wait for the pics
i find the 144 arnt the slowest of growers a cm a month upto about the 5 cm mark then they seem to take off. you cannot really put a growth rate on all of the different types as some grow a lot faster than others i find males grow faster upto 8 cm then they seem to take up a hidey hole and the female seems to grow at a faster rate water volume and diet also play a big part over growding and inbreeding stunts growth aswell as for sexing i always can tell from the shape of them
