Aside from that, it's not difficult to control. Most registrars have a pretty easy-to-use control panel that will allow you to make updates to your domain name, specify who in your company is in control of it, and what name servers it points to. Once it is pointed to the right name servers, your agency can do everything it needs to handle your account.
Unlike most shellfish, oysters can have a fairly long shelf life of up to four weeks. However, their taste becomes less pleasant as they age. Oysters should be refrigerated out of water, not frozen, and in 100% humidity. Oysters stored in water under refrigeration will open, consume available oxygen, and die.
The lifespan on a typical quality glass aquarium is about 10 years with regular use. It's not to say that it won't last 15 or more, but for my money its worth replacing after that period of time. I had an aquarium blow out when I was on vacation a few years back and that one was only 6 or 7 years old. I believe it was an AGA 22 gallon too.
