I had a couple small tanks at various stages of my childhood with goldfish. Knowing what I know now makes me wonder how I kept them alive. I remember, as a child, my Dr. Office having a beautiful aquarium and was always fascinated by it. January, this year I dove in with a 45gallon high. A lot of research and youtube has filled me with more knowledge this time. I now have 5 tanks, 75g, 45g, 30g, 20g, 10g. I truly enjoy creating these amazing ecosystems in glass boxes to learn from, but also to sit back, lost in the Tranquillity of them. I love my hobby!
