Thanks. I think the ones in the video were a few months old. They must spawn in the deep end earlier. I find it hard to believe that the only grow to 1/4 in in their first year. They might. I collected a few more sunfish and have them in their own tank. I caught 8. 3 are 1/2 -1 inch and the rest are ~1/8 of an inch or smaller. I think the ones that ~1 inch were born last year.
Back to the video in the OP. I started with 10 sunfish and I am left with one a little more then a year later. Here is a picture of one the fish fish from the OP video. I think this one is the same age as the 1 inchers I caught this year. Even though my basement is cold the pond I got them from freezes over and is very shallow. That could account for the growth rate.
1 year after the OP video. He went from a 1/4 in to 3 inches in a year. He was the fastest growing of the group by a lot.
