WHITE GRAVEL try darker gravel and he will(as will the other fish) color up more.....fish try to blend to the bottom substrate to avoid predators by blending in....birds ect from above cannot see the fish as well when they blend in to the bottom substrate...same reason why most fish are light colored on their belly...a predator from below has a harder time seeing the fish from below as they blend with the sky.
will do neo
dmack,ya i know about the white gravel but the first pic on this page was when i netted him from outside
but ya my other 3 pbass were the same way,minus the no pattern part.
