I used to have a ten gallon setup as a kid. I got out of the hobby when I was in my teens. About four years ago, after about twenty years with no tank, I took my daughter to the local fair where she won a goldfish. I purchased a sixteen gallon tank for it and began getting other communtiy fish when the goldfish died. I had gotten the bug all over. My sixteen gallon gave way to a thirty eight gallon. That was gave up for a seventy five. That tank gave way to a ninety gallon. Then came the one twenty five which I promised the wife would be as big as I would ever need. I have ended with a two hundred ten gallon which I keep mostly tropheus and petros in. I have a few saulosi in it as well. I keep a large plastic tote in the garage for fry. I am thinking of setting up a tank or two more in the garage.
