I haven't seen hide nor hair of anything.

Most of the spotfins were in the 2.5" - 3" range I think. It didn't occur to me that the perch would be big enough to pose a serious danger - are they?

For the spawning structures, is there a preferred depth? Near weed cover or open?

By the way, the YP are supposedly 2 years old. My thinking is that I'm unlikely to get explosive growth, even with feeding. Am I right in that thought?
