According to their description, C. aeneus has 7 soft dorsal rays, and C. paleatus has 8 soft dorsal rays (there are another differences, as 2 anal spines in aeneus...)

Well, today I have found what a I thought was an albino paleatus, but it has 10 soft rays in dorsal fin...





what it is?


â??â??â??â??â??â??â??â??â??â??â??â??

another bizarre: this has the coloration of an aeneus... but has 8 soft rays ( 1-8 )...



an hybrid?

The last ray is branched at the base, giving the appearance that it is two, sometimes three, rays. I count only 8 rays in the albino and 7 in the normal fish.

Thanks Silurus


you mean rays 8-9-10 are the same, branched...



how do you distinguish a ray branched in three from three individual rays placed together?

If you look carefully at rays 8â??10, you will see that they are joined together at the base.

Interesting discussion. Thanks for the detail picture that helps alot.
Seldom got such info in books i have.
