I did for get to mention the pictures are real good compared to some we see.
Do not for get the more pictures that you provide from different angles the easier it should be to identify, all
within relative reason, since some can be hard to identify until they are fully developed and mature.
must say the female is quite wide so does not look like it will not be long before she wants to start breeding.
Although as we all know this could be at any time knowing what Bristlenose are like... lol.. :P
keep the photos coming and I do not doubt we will try our best to help each other
