i will work on bullhead pics, it does hide alot in the caves, thats why i left both ends of the caves open so that i can pretty much always see em. i only get to see him out of the cave at night. i have a flash light by the bed when the room is dark and the tank light is off i sometimes catch em out swimmin around.the tank is a 75 i just have two hood lamps over top. the grasses and cattails were just put in last week so we'll have to see how it goes. the cattail is sticking out of the water about 6 inches. thanks for the replys all opinions welcome.
