Last rebuild was three years ago. My original tank comes from 1990! Some of my corals are more than 10 years old. My favorite is the big frogspawn. At one time some years ago covered almost half of the tan.
In recent years the hobbie has grow very fast with various nice stores. For some reason I don't understand livestock is cheaper than in the states. Not talking about the local livestock. Supplies are more expensive and some people are buying at ebay and Amazon. We have local shows with some speakers from the states.
