I'm dealing with a tail injury caused by a predator, and I'm looking for some advice on how to treat it. The injury looks pretty significant, and I'm concerned about infection or further complications. Any tips on how to care for it or signs to watch for that might indicate it’s getting worse? Thanks in advance for any help!

Keep the water very clean, and at the first sign of any secondary infection such as redness, fluffiness etc., treat with Esha 2000.
