No, the dyes I have looked at, and i have looked at a heap of them,
did not have copper listed as an ingredient. They get their blue /
green colors etc from another source. I have looked at :
Crystal Blue, Blue Lagoon., Loc Ness Blue, Becketts Blue Dye, Blue
Diamond, Pond Blue, and some whose names I forget. They all state they
are safe for fish and other marine life............
