Today I bought a Dinosaur Bichir. As soon as I put it in the tank it went for my Rope Fish which is almost 4xs the size of the Bichir. Should I be concerened torwards them. Also I have 2 Tinfoil Barbs, 2 Pictus Catfish, 1 Striped Raphael, 1 Common Pleco, 1 Brittlenose Pleco, 1 Featherfin Knifefish, 1 Angelfish, 1 Chinese Algae Eater, and 1 Green Sunfish; none of these fish seem like I should be concerned about. But these are some that I have that do concern me 2 Dalmation Mollie, 3 Tiger Barbs, 2 Gold Gourami, 1 Opaline Gourami, and 1 Sunburst Platy. What fish should I take out (I have an extra tank). Thankyou
