Two weeks ago I started stocking my new 55gal. Currently there are 12neon tetras, 5emerald cory cats, 5 albino cory cats and 2 male dwarf gouramis. One of the DG is the aggressor and one hides a lot. Some days both will be out and fine but over the past couple of days the aggressor has not allowed the other one to eat with out charging him. So my questions is, which one would you get rid of? I like the aggressive one because he is out all day long but the shy fish is more colorful. If I get rid of the aggressive fish will the other one come out and be more active? I also plan to add 9 harlequin rasboras and one angel fish shortly? Thanks
