Understanding potential diseases and how to treat them, is necessary for proper Jack Dempsey Care. If detected early, proper steps can be taken to prevent and treat any disease promptly to maintain a healthy lifestyle for your prized fish. Let’s discuss some common Jack Dempsey diseases just in case.
Hole in the head (HITH).
Hole in the head is as nasty as it sounds. If you just spotted small holes in your Jack Dempsey’s head, it’s probably HITH. But don’t worry, it isn’t a death sentence, but it is a stress alert. This happens due to stress, and Jack Dempsey gets stressed due to dirty water, other reasons include bullying and cramped tank spaces.
Treatment: The easiest treatment is to ditch the bullies and choose calmer tankmates, clean your fish tank more often, and get your fish some space. We suggest switching to a bigger tank if size is the matter. If still nothing works, you could use meds that can fight the bacteria in the tank but this is not likely necessary.
Ick: The white spot disease
The ick is a common parasitic nightmare for Jack Dempsey and many other freshwater fish. Unfortunately, it is as bad as it looks, the sprinkle of white spots on your fish is actually parasites munching on it. This disease can spread like wildfire and promote more diseases in the fish, if not taken care of.

Following these steps and treating the Boxing fish with enough care will make it ick-free in a week or two and your vibrant friend will thrive once again with its full glory.
Fin rot
Fin rot is the bane of beautiful fins. Leaving them tattered and ragged, this bacterial infection shreds the fins of your Jack Dempsey. The fins become colorless and short with fraying edges. This results in both physical and mental damage to our vibrant little fellow.
The main reason for fin rot is poor water quality. The bad water conditions weaken the defense system of the fish, making it prone to diseases. When the defenses are weak, bacteria come in to munch on the beautiful fins. Other causes of Fin rot include fin nibbling from tankmates.
Treatment: The good news is that this disease is treatable. Clean your tank as much as you can, improve the water conditions, and use medication as per requirement. We suggest giving a salt bath to the fish as a home remedy. Monitor your tank and make sure the conditions are pristine. Follow our Jack Dempsey Care tips and use some TLC and within a week or two the fins will be as good as new.
