... We are here to give these animals the best possible home, and anything less shouldn't be tolerated.
Then dump them back in the ocean. :crazy1:
The pet trade in general has this justification behind it that somehow the animal is getting a better life by being removed from it's natural habitat and having whole portions of its reason for existing removed. Probably a result of us putting our own way of thinking into their heads. We figure they'll be perfectly happy is a tiny area (compared to what they'd get naturally), without needing to hunt, without being preyed upon and without breeding. We forget that the animal's whole point in existing is to be part of a food chain and pass on it's genes. We are basically taking away everything they are designed to do. Everything their instinct tell them they should be doing.
Is that the best possible home for these animals? Not really. Dump 'em back in the ocean if you can't tolerate them not having the best possible home (could get rather expensive though since many of these come from half-way across the world).
The other problem with the whole "We have a responsibility to the animals." concept is also, where do you end it? Does it just apply to reef fish, or just the fish you know about? Bad setups by the customer or just the store giving them bad information?
When you go down the list of horrible choices that are commonly made daily in this hobby, without anyone really complaining. The Betta section of any chain store? Goldfish? Large cichlids, Pacus, etc.. Brackish fish in freshwater (Dragon Gobies, Figure-8 Puffers, etc.). Saltwater fish in freshwater (Colombian Catfish, Green-Spotted Puffers, etc.). Arowana. The whole catfish family (Iridescent Sharks, Shovelnose, Redtail, Redtai/Shovelnose, etc.), especially the ones that require a small lake to live in. Turtles. Tangs. Sharks/Rays. Grouper.
At this point you should probably be figuring it is easier to just boycott the entire hobby. And this isn't limited to the fish trade. Rodents, reptiles especially, birds, even cats & dogs.
You can make a full time job out of searching out these horrors and correcting them. Some people do. But, unless a law is being broken there isn't much that can, or really should be done.
