30 years ago I several tanks set up. The standard community fish. I got bored with them. I could find any fish with color.
When I moved 23 years ago I gave up fish keeping. About 6 years ago, my partner at work had many tanks and I got interested again. He ways always on the internet looking at "Fish Porn" as he called it. I started watching over his shoulder.
I ran into a 55 gallon set up at a garage sale in bought it. I set up an African Cichlid tank. Through the years many of the original stocking have died and I now have about 8 very large ones.
