The last couple of weeks, I noticed that some of my reds are developing some sort of humeral spot, like cariba have, or at least a pretty dark coloration in the same area. I read it's not very special, and that it happens more often, but I thought I'd share it with you guys :smile:

First two pics aren't really good:




These are better:




Has anyone else noticed this with his/her reds? Let me know what you all think about it.

I have not really noticed it on my reds, but one of my yellow natts (tern) gets that and it does get really dark sometimes.

Damn, and I hoped they would turn into cariba eventually :sad:


Anyways, I also noticed that it's not always equally more visible, but then, the fish change color throughout the day... Sometimes it seems their entire head turns black.
I'm not worried that it is a disease of any kind: they seem to be perfectly healthy.

Very common, since it was once thought they were the same species until 1993 when the revision was completed. At the time of the recent writing it was hypothesized that cariba and nattereri were more closely aligned and nattereri might be a sister (or subspecies) to cariba because of the closeness of the internal skeletal and the faint blemish often found in nattereri. In 1998, this has now been reviewed and discounted and P. nattereri is indeed a separate, diagnosed species from cariba and piraya. TO add; all 3 exhibit similar traits.

Thanks for explaining, Frank!

Wishful thinking Judazz. :
: My old RBs had the same coloration near his gills. I also thought I had RBs that would eventually morph into Caribas later on from maturity. But no avail.. I dont know what it is also, I guess it would go with their temperment or signs regarding their mood.

I wasn't actually hoping they would transform into Cariba, RhomZilla (although I wouldn't mind :
: )

Was just trying to have a little conversation about this issue, to find out how rare or common this is, what it could mean and what may cause it, and also wanted to hear what Frank had to say about it.
