My favorite uncle used to rear aquariums full of colorful tropical fish. As a kid I really enjoyed looking into the warmed, clear water and green vegetation and seeing those orange, yellow, blue, black, green and red fish swimming around. They were very greedy too and whenever someone came near they'd surface to the top and start opening and closing their mouths like they were feeding. I remember how he'd lean by, puffing away on a cigarette, to tell me things about fish, both freshwater and seawater. Those were very good times I had.
