Greybeard. I wonder why that is your name?

Good afternoon. I know what you mean about sick animals but I think it's different than a sick dog. To me, and me alone, I feel fish keeping is a hobby and a dog is a pet. I know many people feel fish are pets and part of their family but I don't. Most fish in my life are dinner
It is true that many times fish come in sick. But I feel all fish in the sea are sick and carrying something. We as educated buyers just have to pick through them to find healthy ones.
I helped start 3 aquarium stores and am good friends with others and many of their fish come in dead or almost dead. They put the live ones in their tanks to see if they get better so they can sell them but the fish business is not profitable at all and of all the LFS owners I know and have known, they are all barely surviving.
If they didn't accept sick fish from their venders, they would hardly have anything to sell. The owner doesn't want his fish to be sick and tries very hard to cure them as it isn't very good for business.
We can of course not buy from certain stores, but there are very few stores left anyway and I don't think we can afford to lose any more.
LFS could of course not sell sick fish and only sell healthy ones but most of us won't buy a copperband for $300.00.
I myself don't mind fish with some parasites as long as it is not gasping from the surface. I would rather that then have the store drug the fish so much so we don't see any parasites but the fish will never recover.
Of course I get what you are saying and agree with you and we all should be able to get healthy fish.
Just my opinion of course as I know many people will disagree with my opinion.
My beard started turning grey when I was 16. The first people to call me that were not being friendly... but these days? I own that <stuff>. My oldest daughter started seeing grey hair at 14. She hated me for years
My fishes, crabs, conchs... as much our pets as my three Great Pyrenees or our small flock of chickens. I certainly don't buy live animals without the intention of giving them as healthy and happy a life as possible... and yes, we fillet the occasional crappie around here. I'm a meat eater, and have no illusions about where my food comes from.
All fish in the sea are sick. Interesting opinion. I'd have to disagree... all fish are exposed to pathogens, parasites, predators... ok, sure, but a heathy fish successfully fends off such attacks.
Take that healthy fish, catch him in a net, dump him in a dirty holding tank with a fish density that far, far exceeds anything in nature, change his diet, take away his hiding places... one stressed fishy. Now, all of a sudden, that healthy fish no longer has the resources to fend off the same parasites and diseases, which have happily multiplied in numbers, what with all the stressed out fishes concentrated in these holding tanks.
That's where the problem starts. It's _THERE_ that we need to start to fix things, and I'm certainly not the only one that thinks so.
A decade ago, that beautiful fish you picked up at the LFS was likely teased out of the reef by blowing cyanide into his cave. Will it kill him? Sure, eventually, but the collector, exporter, wholesaler, and retailer have already gotten theirs, so who cares?
WE DO! And, I'm happy to say, cyanide fishing, while not totally gone, is far less common than it was a decade past.
most of us won't buy a copperband for $300.00
Really? I would. If I knew that the vendor was doing everything they could to provide me with a healthy fish, and not just pocketing the profits... I'd be happy to. Biota is selling captive bred yellow tangs for close to that $300 price point, and having no problem selling them. There's no way I could set up and maintain a quarantine system for less than $300... why not? The biggest selling lights on BRS are > $600 each, and usually sold in multiples. It's certainly not a rarity for our hobbyists to spend big bucks. I'd guess over half the daily visitors to this site have something north of 5k in their systems. I know I fall into that category. Three bills? For a HEALTHY fish? Unlikely to infect my tank? Something that's chances of living are > 80%? Please. Take my money.
I respectfully disagree.
Been keeping marine aquariums since the early 80's. Have known many LFS operators, had friends open shops, etc. Yeah, it's a tough business. Today? Even more so, what with online vendors. A good one, one that quarantines themselves, or is at least willing to do so, at a price... is a treasure. We had one... but like most really good LFS's, the guy running it was more a hobbyist than a salesman. He got burned out, and shut it down.
