When carnivorous fish consume toxic herbivorous fish, the toxins can accumulate in them as well, allowing the toxins to biomagnify up the coral reef food chain.
The main reason behind this rapid lose is that Cr(VI) not only cumulated in tissues during aquatic organisms growth (bioaccumulation) but also biomagnify up the food chain and thus fish faced both metallic stress as well as starvation.
