Hi Stefanie.
I think I speak here for all, that we really try our best to be helpful. I certainly do, – but it is really difficult to be 100 percent certain of this on the basis of photoes, – and I must say, the images you have showed earlier, with my experience looked very much as a male.
In the last image – if this is the same fish, it shows those signs much less, – now you say it, yes the band in the caudal fin is vaguely visible. But at the same time this fish shows no other real clear signs of being male (except for the vague band) – and to me it now (which has been the confusing point all the way) shows many more clear signs of being female (that would be the bodyform, the lack of colours in all other fins)
With all our experience and good intentions it is obvious that sometimes its just not that easy. Martin gave you his opinion, and to me it sounds like he was rigth indeed, – so its pointless to argue just for the sake of arguing, – I for one have learned through this thread that a female can indeed show male characteristics in the absence of males, – more than I thought.
I am sorry for having perhaps giving you false hope that it was indeed male, – I honestly now must say I have to correct myself … – I was fooled by the fact that it showed more intense colours than I have seen in a female before
