Hi all.
I got 4 Metriaclima estherae, Red Zebra, a while back and one had a black smudge on its forehead and face when I got it. I thought it may have been diet related and may fade but it hasn't. What causes this? Someone told me ages ago that the males have it. True or not? Or is it caused by too much inbreeding? I know some E.yellows can show a 'shadow' on the face because of indiscriminate breeding. The other 3 fish , and the older one that I already had, are clean and brighter.
This is with flash and makes it look worse than it is....
