Can you please tell me why my fish disdus change to dark color and it does not eat about a week. It doen’t seem sick, acted normal. I keep it with 3 other discus those are eat a lot. Is it okay to keep a baby silver arowana together with discus fishes?

The fish changes dark in color mean she is not feeling well. She will be sick later on. Put her in a hospital tank. Treat her with Acriflavine solution plus salt. Change water and repeat the treatment for a few days. It will not be okay to keep Arowana together with discus fish.
