Hi Mike, Yes it did change colour to start with, when stressed, but I haven't seen it do this for a few months. Here is another pic taken the day I got it back in Sept. 2001 when one of the angels was paying just a little too much attention to it. It is showing that mottled colour pattern here. I guess that does it then - Hongsloi it is - Thanks everyone 8-) http://svavevav.idx.com.au/images/APISTO8.jpg If this female is showing male characteristics and I introduce a male will; - the male react aggressively towards it? - it revert back to female colouration? - she be able to breed still? I have heard of gender transformations in Apistogramma and Dicrossus - is this the start? I was under the impression this didn't happen unless there was a few individuals al of the same gender though. Are hongsloi harem spawners - would it better if I got a few more females too?
