Grammistes sexlineatus Thunberg, 1792
Grammistes sexlineatus, or the golden soapfish is a toxin producing fish closely related to groupers(used to be placed in the same family, Serranidae. Now in its own family, the Grammastidae.) These guys have a blasting radius with their anxiety attack(a literal attack!). While not enough to cause harm to humans, the toxic grammistin secreted from a soapfish's skin when stressed is used to deter predators and can even kill other fish when kept in captivity. That last part I always see mentioned in literature regarding soapfish, seems to me that some early ichthyologist had an unpleasant experience when trying to keep one as a pet… Grammistin has a slimy consistency and even tastes bitter(who's out here licking soapfish???) which is the reason for their common name.
