Damn, I'm gonna write an essay here probably lol....
In a way I feel this discussion divides us saltwater guys as well...
We see this is in the car hobby also...There are alot of people out there with the cashflow to make things happen, pay for the nice ride, pay for the upgrades and someone to do the upgrades for them, and drive around in a 800hp car with a big grin all day...
Compared to the guy that gets saves his money for a long time, gets the car, slowly does mod's as he can afford them, slowly building it up, doing the sweat equity himself, until he eventually has a masterpiece he created.
I'm big into cars, and saltwater....so I can see how these 2 hobby's in this way collide. For example, I'd like to paint a picture for many of us here....
We have many saltwater owners, that see a reef setup in a store, the gf/wife is "oooooing" and "ahhhhing" at it, as well as himself...He pulls out his credit card and gets a big tank, lighting, everything off the bat...the LFS sets it up for him and provides a waterchange service for them and takes care of there tank on a regular basis, like a house maid takes care of a home. He then walks around the store with his gf/wife picking and choosing "ooo that one, this one, that one" to various tanks. SPS, LPS corals galore, this fish, that fish "OOOO that seahare is really neat". The LFS owner grin's away with big dollar signs in his eyes. Maybe a few suggestions as to what will or wont, or "might" not work in the tank. But no biggy, if it doesnt work out, its only 20-30-40-50 bucks right. Majority of things in the tank will survive. The lfs puts the corals in his tank, or he does, with minimal advice as to acclimation, etc...he puts his favorites where he can see them really well in the aquarium...Not aware of flow or the proper light parameters....Things look good, great actually...Then a few days....to weeks....things dont look so good anymore, shiveled, melting away, the acro's he got are turning white? why is this? The lfs employee comes over, and adjusts corals accordingly some are already on the way out, but he assures the guy that its the nature of the beast and some "always" die due to "transport and stress" Over time, things have died, the mandarin dragonet was toast after a week, the seahare seems to be "hiding" when its actually dead...
We can all see where this is going....
You now have the reefer like many of us here...many of us, like myself sit on this site trolling for information, after 2 hours I stretch and wonder why I just read 90 pages on a DSB debate and favorited 10 different sites....I was just like that rich guy, "oooooing" and "ahhhhing" in the LFS, and at my friends tanks...But I spent months researching first, got a 2nd hand setup, used for a good price, did it slow, and got the best damn protein skimmer I could fit in my sump lol...Most importantly I have multiple books now including the bible "the book of coral propagation" not to mention the endless amount of fragging knowledge online.
While greenbean is right, we cant sugarcoat a negative thing. Mainly the fact that our hobby contributes to destruction of the natural reefs. I personally believe we can all bring out many positives with our own home aquaria. Many species of corals that were unheard of in home aquariums 10 even 5 years ago, are now flourishing today in peoples homes. Not to mention the fact the enthusiasts like myself are technically unliscenced scientists in many ways. Through our own efforts we've found ways to feed a certain fish, or a coral like a sun coral and with proper care made a non-photosynthetic coral thrive because we nurture it back to health from an owner that didnt have the time or knowledge to raise it properly. Many owners have contributed to coral id's from the ocean, Expecially Acro's. Most importantly certain crabs being id'd that host in a single specific coral, which sometimes is in direct relation if that coral survives or not...Building an archive of those crab's so we can breed them for certain corals...We've found out ways to propagate corals in such a manner that we've contributed to lesser demand of that species, meaning more left in the ocean.
Our destruction like everything else is based on supply and demand. If we all do our part with propagation and opening doors gently with new owners by giving proper advice or incentive to come here and learn/research themselves. If more of us have the balls to stand up to the guy at the LFS and tell the customer she cannot have a "nemo" and that pretty lionfish... I believe we can truely minimize our impact on the reefs.
So for the OP in this thread or to anyone else brought on by someone "smack talking" your aquarium, you can gently explain to them, that you as many others do everything in your power to buy aquacultured, or species propagated from your local forum. You also propagate your own corals to minimize your own impact on the reef. Once you explain what propagation is, and how you can create multiples out of one coral, by going into detail about how to implement surgery on one coral, and how different tactics and ways of cutting, breaking, sawing, are used for different corals, how you spend so much time in caring for these creatures...and after a month be able to provide that species to other owners, quenching the thirst of destruction for a few corals in the ocean...that you yourself are against the destruction of reefs and you're doing all in your power to minimize the supply and demand of species... then explain on a whole how many responsible reef keepers are out there, How technically we're all working together, maintaining our own saltwater "zoo's."
It's a pretty positive light to shed.
All I can do is NOT be naive, understand my contribution to the destruction of reefs, research and propagate. I know within the next year the amount of frags I've sold or traded, or even given away...will far outweigh my wild caught purchases.
We can all act as a team, and slow the demand....eventually slowing the supply. We just have to set a bar for ourselves. I think 10 propagated per 1 bought is a fair compromise. Unless you buy aquacultured or propagated...Speaking personally I have 2 friends that have saltwater tanks, we all buy different species, and are in the process of fragging the species we can, and giving each other the ones we dont have. You purchase 5, you get 15 through propagation. I personally believe this is the answer to our worlds reefs. No we wont "Stop" the destruction completely but we can definitely make a statement to the world and the company's that are collecting from the reefs. And minimize the impact ourselves.
I'm content with my position as a saltwater hobbyist. I will also not hesitate to step into the firing range with someone against it. I myself cannot stop it, but I can do everything in my power to fight it. At least instead of bashing a hobby, I'm actively helping it through propagation. One person propagating is a tiny impact, thousands...a big impact.
Evolution of our hobby will soon enough be owning a propagated tank. To be able to look at a person "oooooing" at your tank and tell them, all the corals in that tank were captive bred, propagated or aquacultured species, and that not of of those corals they're looking at came directly from the ocean.
A reef tank that didnt contribute at all to the destruction of our oceans....It's a future I'm planning on being part of. It just may take a while to get there.
