A lot of people tend to get confused as to what a "true" salamander is. Techinically speaking, a salamander must contain the white butterfly pattern on all 3 unpaired fins AND ventrals, and must contain a body color that is different from the colored portion on the fins. For example, these males are outstanding-
You can see how they've got the BF pattern, then yellow hued fins, then an almost iridescent purple on the body. Your male was a pretty good salamander specimen, but in order to keep the strain alive I'd breed the girl to a mustard gas, as this is where the original salamanders derived from. So, yes, you're correct.
