I just feed my rpb whenever. Sometimes it is a few times a week sometimes it is weekly. They feed on opportunity in nature not by schedule. When I go several days I tend to feed more when I do. I had been busy a several days at work and hadn’t seen them in almost a week in the light when they were awake. When I did I fed them a whole bluegill the size of them. They ate the whole thing and loved it. They are about 8-9 inches when I measured them last week. I really need to make a feeding video. They are the most personable rpb I have heard of and come to the glass when I walk by. Not skittish at all.
