Believe it or not WE have the power.
Only by agressively spreading the word to everyone we see, i.e. "How's it going today?, by the way, don't buy from PetCo." for example, will WE start to make a difference.
I, personally, am willing to pay more for properly aqua-cultured and cared for aquatic life. I think of it as a reward to them for doing things correctly.
Some fairly good online stores are Aquatic Warehouse of San Diego (Seen them in person) and Reeftopia.
Marine Depot are a mix of good/bad service, and average quality marine life.
Reef Tank/ Reef Store in Virginia is a mess. It is an agal cesspool, with every frag teeming with flat worms, and I'd never buy from them. I'm disgusted everytime I wonder through their store (in hopes they've cleaned up their act)
Marine Scene in Virginia is another "out for your money" store. I've often stopped to listen to the advice given by the employees to under-informed reefers, and just chuckle away. "Push products," is their motto. But, hey, it's all about the dollar, right? They do take petty good care of their fish however.
Roozens in Maryland is a reef "flea-market" that looks like they use water straight out of the tap, and have their critters cooking in a greenhouse, outrageous!!! Not to mention the lovely rudeness by which they welcome you into the store. My vote, boycott. Aiptasia, flatworms, parasites galore....... Basically a ceptic tank.
Harbour Aquatics was a "no-show" the two times I attempted to buy from them, so I cannot attest to their quality, obviously, service sucks.
DrMac really came through with some exquisite corals in a very timely fashion, offered great over-the-phone advice, and was extremely personable. The quality of his frags and his packing techniques are unrivaled. He charges a little more, but it's worth it. He always gives you person-to-person service directly. He is an eminent pro in the industry. But then, most of us already know that. I will only buy acros from him in the future.
