I bought this little one 6 months ago as a female. She was white with a little bit of red. But she was too aggressive for my big tank, so now she is alone. She is very colorful now (iridescent blue, red) and her fins are bigger.
A friend suggested that it was a male, now I have doubts. Any opinion ?
