New to the fish world been fishng my whole life and had all kinds of different animals but aquariums are new to me. I got alot of friends with some serious tanks who are helping but I like to get as much feedback as possible I hae a super basic tank 45 gallons no real decor yet. Just got a Columbian Shark and the wife got some mollies which I intend to have eaten. Any suggestions on decor or fish please do so
