Hello all - I am looking for some good tank mates for my angel fish. I purchased 3 today, and they are currently in a tank with a blue channel cat, 3 columbian sharks and an algae eater. They are all housed in a 30 gallon tank. The oldest fish are my sharks and the cat (have had them for 1 month), and I plan on moving the cat to a MUCH larger tank, and the sharks to a brackish tank, leaving my angels virtual mateless. Any good suggestions?
