They had their first sucessful batch of babies a few weeks ago a photo of one I posted in this forum! They are completely different colours as you can see - Mrs BN is a patchy white colour and has been for the year ive had her - Mr BN is greeny colour at the moment!
It never ceases to amaze me how much they can eat! - that is a huge wedge which they completely devoured in 1 day between them! All of the other fish mill around waiting for little pieces to break off so they can get some - infact my rainbow fish hovers and tries to chase the others off!!
