bristlenose Markings...

Post by butterfly »

I'm not sure where this needs to go, so somebody move it if it's the wrong place :)
I saw a beautiful long fin albino at aquabid.com, the seller made a remark about a red "V" at the back of the head. Of what significance is this?

There is a red mark on the back of when they are albino. [At least the ones I've bred have this mark - don't know if there are any that DON'T].

Yep mine do too, but it's just a spot and this person was specifying a particular shaped spot. It was "V" shaped and the picture shows that. I was wondering why the "V" was significant. I finally e-mailed the seller and his response was that all his males have that red "V" shape on the head. does that make it a different species? Don't know. Just made me curious.

Hi,

in my experience, the size, colouration and shape of this spot depends on moods.
When the fish is completely fine, happy with everything and just relaxes under his piece of wood, there is hardly any spot visible, it´s somewhat orange, small and looks like a simple spot.
But when the fish gets excited (either, because I want to catch it or a nice girl is nearby) the spot becomes very pronounced, v-shaped and red.

By the way, I´m talking about the xanthoristic "version" of A. sp. (3).

Thank you for explaining that :) I have never seen that particular marking in my albino BN before and it roused my curiousity.
