When in doubt, consult the original description....
Yup, thats what i did... right after i wrote this post (i know i should have done it before...) and... now i have to correct myself
I had another picture in mind when i wrote "C. steindachneri looks different". I cant say that because the picture in the original description is not very good, even if the paper is not copied. The holotype was preserved ~ 50 years at the time of the description, so there isn't much of the colouration left. Unfortunatly there is no colour description of living fish given in the paper and afaik there isn't any dependable till today.
However the rest of my post stays and like H.H. wrote the body form differs (althoug there is a great variability in C. paleatus too) and the fish is (imo) a breeding form of C. paleatus.
