Please note that I am not a vet, and have no formal training in diagnosing Betta fish. I am just a Betta fish owner with over 20 years of experience. While I’ve had success with these treatments on my own Bettas for the past 20+ years, this information does not take the place of a licensed veterinarian.

There are a variety of Betta illnesses that your Betta fish can catch. You will generally need to isolate your sick Betta. This will let you safeguard the remaining fish just in case the illness can spread. be careful to not have a sudden change of water by using water that’s been left out and at a similar temperature for a minimum of 8 hours.

Prevent the spread of your Bettas germs by washing your hands with a purifying soap after treating an ill Betta fish.

Determining the symptoms of your Betta’s illness is critical to giving him the correct medication. When you know out exactly what your Betta fish illness is, review Betta Treatment of Illness for the best treatments.

A healthy Betta should be vigorously swimming in his tank, while an unhealthy one usually stays in the edge of the tank or even near the bottom and only rise for air.

Betta Symptom – Clamped Fins
If your Betta’s fins are always near his body, then he probably have clamped fins. Clamped fins is a sign of bad water quality. Start substituting half of the water every day until water quality improves and his fins are healed.

Illness: Ich
Ich is a serious and contageous parasite. If you notice tiny white dots on your Betta fish’s body, he may have Ich and require immediate treatment. A sure sign of Ich is if you notice your Betta swimming against items in the tank so it can wipe off the parasites.

If your Betta is highly stressed (possibly by competing fish or inconsistent water temperatures), this can make him more likely to Ich. Just like in humans, Betta fish that are stressed usually will have many more illnesses.

Betta Illnesses – Fungus
Grey or White spots that is bigger than small spots is a fungus infection. It could if untreated turn into a fuzzy white looking growth.

Betta Disease – Tail or Fin Rot
If your Betta’s fins look like they are rotting, shredded at its tip, or have holes inside them, then he most likely has Fin-rot. This is a very common disease a lot of Betta’s contract and should be treated as quickly as possible. It’s a bacterial infection that can quickly pass onto the rest of the body. In really terrible occurances, the fins and tail may begin turn red or start to bleed.

Illness: Constipation
Bettas will be healthiest when eating a wide variety of food. Take a look at the Betta Food Article for guidelines on what to feed your Betta. If you notice a protruding abdomen, but besides that your fish is swimming normally, then he may be constipated.

Betta Fish Sickness – Velvet
Velvet can be diagnosed by the gold and yellow powder like dust that is on his body. It is best to shine a light to try to spot it – it’s tough to see otherwise.

Disease: Dropsy
If your Betta fish has raised scales and a large abdomin, he may have contracted Dropsy. For really bad cases, when looking from above the scales may appear to be similar to an open pine cone.

Betta Fish Illnesses – Popeye
If you notice your Betta’s eyeball popping out, if it’s foggy or has a bubble covering it, then he has gotten Popeye. It’s quick to spot and very simple to treat.

Illness: Tuberculoses
Tuberculoses is the only known disease that a Betta can transmit to a human being, so be certain you don’t have any open cuts and are not ill yourself (with a poor immune system) prior to submerging your hand in the water, or better yet put on clean gloves. Do not be too concerned – the worst that can happen is give you an infection.

Signs of Tuberculosis include:

* Scales falling off or sticking out
* Weight loss and no appetite
* Skin discoloration
* Clamped fins
* Lack of swimming
