My footlong black arowana jumped to hard against the lid of my tank, and lost about a silver dollar sized patch of scales on her side. Looks like only the first layer, but it was very upsetting. :22_yikes: Its been about two days and she hasn't really healed up yet, and im wondering if anyone has any experience with something like this. Mabye something I can do to help with healing. Shes in a 210 gallon tank, with a 6.5 ph and perfect water quality. I add a little salt, and Prime when I do water changes. She eats crickets and Krill, but prefers crickets. Awsome fish, but im worried. Any input is good.
