This was my 300 gallon Reef Aquarium. It was up and running for almost eight years.
Everything in the tank was real and alive. The largest clam was about 14" long.
The above picture was December of 1999, below - November of 2000
In late 2003 I finally gave up on maintaining it. I couldn't give it the time it needed or deserved.
Many of the fish survived from the first day to the last and are now living in a display tank at a local aquarium store.
