haaaaa phil his tank has 2 402s at the opposite end,but unlike my smaller guys this big one stays out of the current. temp is 73*...he is 18" and has a bluegill fetishMan, he really colored up nicely since you got him. Awesome darkening to match up to your dark gravel. Can't wait for a yawning pic to catch a glimpse of his dental work.
Have you tried a powerhead down near the bottom to give him some exercise and help purge his muscles of lactic acid buildup?
