injected fish colors

Question
You, or someone, just mentioned that glass tetra are injected to get the beautiful colors; are neon tetras or cardinal tetras injected?  I sure hope not!

Answer
Dear Susie,
Yes,  Glass Tetras are unfortunately injected, but the beautiful Neon and Cardinal Tetras are not! They are gorgeous in their natural coloring, but I also think the  Glass Tetras are beautiful in their natural appearance without the dyes.
Happy Fishkeeping!
Karen
