Generally, Gerbers has higher overhead than other places like Coral Pets. However, you get something at Gerbers you can't get elsewhere; variety. Example: recently I bought a blonde naso tang, a desjardini sailfin tang, and a yellow eye kole tang from Gerbers. The price was about 10% higher than other places, but IMO the livestock (fish) is healthier and seem to live longer. Plus, if you want a purple tang, it's nice to have 5 to see, feed them, and pick the one that eats the best. Thats the advantage of Gerbers. All of my fish except my shoal of red spotfin anthias came from Gerbers, and they are going strong. I get my other fish from Phishy Business in Columbus.My melinarus wrasse came from Coral Ranch, but Rich is long out of business. I go to Marine Solutions for food and corals, and Premium Aquatics for those items I need NOW that everyone else doesn't carry.
