Other then the feeders and crayfish from my daughters school.....
I bought 3 Giant Danios that are still living well in my 100G. They have made the transition from 10 --> 20 --> 100G homes
My very frist fish was a regular fishing minow. We had one minow left over after fishing. I put it in one of those large pickle jars. I had it for a long time. I got my frist 10gallon for that guy. I miss the old days. NOT
When I was 3 I had a betta named Tomata. I named him that since I had trouble with just betta. He lived in a glass bowl and I was terrible about over feeding(since I was 3).
