with all that dark barring they look stressed out do you have some dither fish in the tank or maybe a plant floating in the water they will calm down and make it much easier to id
Well, do your pbass eat until it's "content" or does it stuff itself? When my pbass eats too much (sometimes to the point where it looks like its going to throw up), its colors either get dark or its colors fade
if they're on feeders, not really much you can do.. eventually they'll outgrow the size of your feeders and they'll feel more comfortable swallowing a fish then
