He is quite acclimated to the tank.. pretty much stayed one in spot the first couple nights, but hes pretty much in a different spot every morning when I turn the lights on, and I've seen him bathing/'out and about' at night. Just over 3inches from front to back, hes put on a little weight since I first got him. Most of the tank setup came from people here, which I give my thanks, I like the eco earth a lot better than the moss I had in there. As far as the feeder fish, I've been keeping plecos and predatory fish for almost 8 years and I take precautions with feeder fish plus they are dusted before fed and not every night. His main diet is night crawlers, crickets and fish, I haven't decided whether or not to add pinkies to his diet or not.....I haven't yet.
Edit - Guess I should clarify, not all those feeders are the pac's, toward the upper left hand corner of the tank.. the two larger gold colored fish are a type of molly, theres 5 in there and those are the pac's food, the rest my wife gives to her Piranha.
