For the last 24 hours, there have been a lot of fish flopping around near the drain to the river. They periodically flop over the rocks and swim away.
Anyway, when I went to actually investigate I see 7-10 fish in this small area and they're flopping around a lot. I moved a few rocks so it was easier for them to get out and encouraged several to move towards the exit, but there were a few that refused to leave. I left them because at least it wasn't overly crowded now.
