Serrasalmus Compressus?

[ativa01]

Received two 3" S. Compressus. Each have distinctly different characteristics. #1 features a flatter, less angled dorsum, smaller in height (more "compressed"), larger eyes/iris, darker/thicker terminal band on caudal fin, larger spots which are darker and more rounded. The other with opposite characteristics - more angled dorsum, longer height, smaller eyes, terminal band on caudal fin is much more faded, and a brighter overall appearance with more noticeable gold "fleck" and lighter spots which are more oval in shape.

I believe they are Serrasalmus Compressus but my friend disagrees. And the different features strike me as weird but I have not kept this type before. Opinions?

Seem like it to me. I don’t know serras too well though.
Great find! I had a chance to get one a while back but passed on it, regret it knowing how rare they are.

Should not be kept in the same tank with out a divider at least.

Yes, I know. This was just before adding egg crate.
