BD,
The night feeding thing makes sense but my bass are on welfare. That is, they are so used to the pellets I don't believe they do much night feeding but I could be wrong.
Houston,
I got the bug feeder from an outfit in Colorado but you can get it from lots of suppliers. It's made in Wisconisn by the Fresh Flow company. It's listed and pictured on the following site:
www.aquaticcontrol.com/ Not sure if other's sell it cheaper. There are other bug feeders such as the bugslugger and bugomatic. I haven't tried them.
