Pond Boss Forums INTRO Questions & Observations Is it normal........fish sunbathing?

for bass & bluegill to sunbathe??? Over the past few weeks with the cool evenings and warm days, I've observed the fish just below the surface hovering. They appear to align themselves with the sun. I've even seen the fatheads do the same. Perfectly aligned lengthwise with the sun. It doesn't appear to be an oxygen problem as they are not gasping at the surface....just sunbathing. Everybody is feeding as normal. Do I need to apply some 30spf or 45spf???......LOL Chuck
