there really aren't any humane ways of catching the fish. hook and line, nets, or fish traps seem to be the only other options. fish traps are particularly cruel because once a fish gets in, it can't get out. if the trap somehow gets loose and the fisherman isn't able to retrieve it, it just continues to catch fish until it finally (hopefully) falls apart after a couple years. i think i read a study that said one lost trap can catch over 10,000 fish in a year. when a fish dies, the other ones eat it, and new fish are attracted by the other fish feeding.
Look for bright colours,gasping or overly timid behaviour. Always look come back etc. I usually ask my fish shop to feed any prospective purchase prior to purchase. If they balk walk! It also helps if you really know your fish shop most of the good ones only buy from one or two sources. They also keep their fish in qt for a good 14 days ,"you should always give them at least that much more time in qt!"

I've been buying fish online for years from 2 well known sources. I will never do it any other way. The price, service, guarantee, etc., are unbeatable. Find a friend to share shipping and/or minimum order requirements and you'll never go back. It isn't possible (IMO) for anyone to be 100% sure a foreign supplier didn't use cyanide, the problems show up down the road. I think a lot of the fish that just die for no apparent reason are the result. But; I know the dealers I use do everything they can to avoid cyanide caught fish; including sample autopsies by biologists. Australian, Caribbean, and Hawaiian fish are generally a safe bet.I don't think my LFS QTs at all. But then again they don't seem to do anything right. They even tell you not to use RO water or sand. LOL. O personally would be more comfortable buying fish from a well known website.
