Check out the book "Marine Fish" I forget the author but it has descriptions or 500+ species of salt water fish. They talk about it in the beginning. The book is like $19.00.
Cyanide solutions are used extensively to catch live reef fish for consumption and ornamental purposes. The concentrations of dissolved poison are not meant to kill but only to tranquilize the target fish, which facilitates their capture. The live food-fish trade concentrates on the catch of groupers and Napoleon wrasse. The aquarium fish trade concentrates on a much wider variety of species of colorful reef fishes (like the ones in your tank). Live spiny lobsters, are also caught with cyanide. Cyanide fishing is done by divers, using "hookah" compressors and hoses to supply air. A diver on a "hookah" compressor-hose descends 10-40 meters until he spots a target fish. He chases the fish into a crevice in the reef and then squirts cyanide from a plastic bottle into the hole. As the fish begins to weaken, the diver breaks away the coral around the hole, reaches in, grabs the fish, and slowly escorts it to the surface. The cyanide fishery for aquarium fish destroys large areas of corals, which are broken down after an area has been sprayed with cyanide and the target fishes have fled in between the corals. The use of hookah compressors is a key factor in cyanide fishing practices.
Unfortunately these guys don't have gills themselves to take in the cyanide as well haha.
It's called FISHING for PROFIT, they don't care about the fish, HENCE why when you buy from places like ***** they rarely ask you questions.
Questions that should be asked would be, How big is your tank, how many fish do you currently have, do you have any invertebrates (because some fish will eat corals and stuff)
Think about it...
