To think this decorative fish could be eaten! Good solution to plagues. Next dish: rats please (to help prevent Lhasa fever, currently plaguing Africa, and carried by rats). Ok; you don't fancy rat (why ever not? They eat guinea-pig, don't they! - in Peru). How about ratFISH?

My fishmonger's had one on display last Friday! (NOT my photo above. See credit - but they look more weird on dry land than in the water, hence this photo is the best.) But you CANNOT EAT them! (The specimen was not for sale.) I forget if they were poiisonous in any part, but I think it was that they were basically only skin and tiny-winy bones.
It is NOT a flying fish (way too big for such a trick).
