N rachovii dorsal fin colour

[LeonZA]

Hi,

I am looking for a certain strain/population of N. rachovii that I saw once in a local pet shop about 6 years ago. It had a greenish/blue(very green) dorsal fin, but I can't seem to pinpoint the correct one. It nearly looked like the first rachovii picture inside this link:

Is this the aquarium strain or Beira 98?

The reason why im asking is because nealry all the pictures of Beira 98 show them with blue dorsal fins. (some show a little blue/green colour)
Although it seems that the aquarium strain also has a blue dorsal fin when I do a google image search.

Is the colour related to strain/population differences or does it have to do with lighting conditions, food or age?

O btw this is my first post

Any reply/help would be appreciated.

The fin colour you mention depends a lot on the lighting. In general, the fish of the Beira 98 population vary from bright blue to green-turquoise depending on lighting, age, time of day etc...

If you like, I can arrange some eggs of the Beira 98 for you. I have a small breeding group spawning right now.

That would be great

Thank you very much for the clarification on the fin colour.
