We all know how difficult it is to identify the sex of these fish, so please post a picture in here and we'll try to help you (or at least give an educated guess!).
Sorry, not very good photos of my over 3 yr old zebra - approx. 7-7.5cm
If I can establish the sex of this one then I will attempt to get pictures of the other adult. (The small zebra in the first photo is only just over 12 months)
Although it is always in a cave, I am not sure it is male. What are your thoughts or do I have to take it out of the tank to get a better picture.
Thanks
pic one looks like a male, pic two looks like a female... very hard to say. but i think it is a very fat male, because its very hairy. does this pleco always stay in a cave ? If it`s, it`s definitive a male !!
Yes it is always in a cave - the reason I wasn't sure is that it has a huge belly lately and looks more and more like a gravid female, perhaps wishful thinking of my part
I would say gravid Female. My breeding Female that has laid eggs spends all her time in a cave. The only difference is that she usually sits at the front in view where as the males sit right inside the caves out of view.
I am thinking more and more that I have two adult females. If the one pictured is gravid and there is no male - will she absorb any eggs or could her health be endangered.
Why I think I might have two female is that both adults don't appear to have 'bristles' of any sort and, I would have thought that they would have some at their age.
