It's quite horrific how badly fish can be handled....its not every single LFS, breeder or transport firm that does it, I think that needs to be remembered here, there are some exceptionally good places to buy fish
Sometimes I feel that a fish is looked upon as inferior
You can't cuddle it or take it for walks or play with it like you can a dog or a cat or a hamster etc
Its "only a fish" so what does it matter how its treated? Why bother checking for diseases etc cos its "only a fish"?
We have no real idea if a fish feels pain or is unwell...it doesn't yelp at you or scratch you or bite you (unless a Piranha of course).....they are living, breathing creatures who get sick, get hurt, have bad days, who sulk or act like lunatics...
As with any animal, they take alot of care, often alot of time and money and they can be emotionally draining when it all goes wrong...these are not "ONLY A FISH"
They deserve better than to be stuffed into a cup or an aquarium where they can barely turn around. We as humans are their voice, their guardians. Fish deserve as much respect as any other living animal and that includes mapping and tracing disease traits, improving their catching/shipping/breeding/showing conditions and better education of those who work in stores that sell them and those who own them.
