I recently bought a 55gal tank. The person selling it had fish and asked if I would want them. Of course I would take them and so I did. The tank came with 2 Silver Angelfish , 8 rummy nosed tetras , and a bengal loach. I was thinking after giving them some time to adjust and the bacteria and chemicals to get to normal I would ponder on another fish to get. These fish arent fish I would buy as they arent very cool or pretty imo other than the bengal loach is active and very sly and beautiful. What are some options of fish that you would think I should consider being that I have these fish already.
