 This has given rise to the collective common name "dream fish" for ichthyoallyeinotoxic fish.The species most commonly claimed to be capable of producing this kind of toxicity include several species from the genus "Kyphosus", including "Kyphosus fuscus", "K. cinerascens" and "K. vaigiensis".It is unclear whether the toxins are produced by the fish themselves or by marine algae in their diet, but a dietary origin may be more likely.
