I had a 20g Long as my first aquarium when I was 11 years old. Back then, the rule was 1" of fish per gallon, and I didn't like that rule. So instead of worrying about any fish, I decided to make it an invertebrate tank. There was no limit to how many you could add, which was awesome.
Today's club meeting was at Oceans Avenue, and they did a fragging demo workshop for the club members and customers. As we watched, they cut various corals and then used glue to mount them to frag plugs. A grill was out back, providing burgers, hot dogs or chicken to everyone.
