I got 6 new brochis today, got them home, acclimated and released and noticed one that has redness/bruising to its fin right behind its gills. Although the netting went smoothly, it did take three attempts with one of the fish. I have no way of knowing if it was this one. It is pretty active and alert and is all over the tank with its buddies. Should I do anything other than observe? They are in quarantine right now. Thanks.
