Hi. I have my 50 gallon tank with: - 5 rummy nose tetra - 5 neon tetra - 4 tiger barb - 5 zebra danio - 2 mollies - 1 rainbow shark - 1 dwarf gourami - 1 dwarf crayfish I know its getting full but I want to get an angel fish or two. At petsmart they told me they would eat my smaller fish. Is this really true? Ive seen videos of angle fish in community tanks with the fish i have. I really want to get an anglefish fish as a centerpiece.
