You may be wondering why vertical death happens in your aquarium fish tank. The good news is that most of the time, you can prevent your betta from falling victim to this terrible fate. The bad news is that even though it’s rare, it can still happen. If you haven’t heard of the term vertical death before, you’re not alone. It’s a phenomenon that many fish keepers are just learning about now. But don’t worry – we’re here to help!

What is Vertical Death?

Vertical death is a condition that occurs when a fish swims up the side of its aquarium and dies. This happens for a few different reasons, but the most common ones are poor tank conditions and diet. If you’ve ever had a tank with fish, then you’ve probably heard of the terms “sick fish” or “sick betta.” Sick betta fish are often those who have high ammonia levels. If your betta fish is especially hardy and isn’t affected by the high ammonia levels, then it could fall victim to vertical death.

Betta Fish Tank Setup and Parameters

When setting up your betta fish tank, make sure that the water parameters are perfect. The water parameters we’re talking about are pH, temperature, hardness, and water chemistry. Check your water’s pH, temperature, and hardness, and make sure they’re both where they should be. You can also keep an eye on your betta fish tank water chemistry. If you live in a climate with heavy rain, you may need to add a buffer to your water to prevent it from becoming too acidic. If you live in an area where the water is hard, then you may need to add some salt to the water to soften it up. You can also check your water’s hardness and make sure it’s at the level you need it to be.

Diet and Nutrition

When it comes to diet, you’re going to want to go for a varied diet. If you only feed your betta flakes, he will get bored and frustrated very easily. You should also vary the types of foods you’re feeding your betta fish. Keep in mind that betta fish are Omnivores and should be fed a varied diet. They love almost anything. Crickets, Hikari Macrocrystals, Blood Worms, Hikari Shrimp, Hikari Frozen Bloodworms, Hikari Brine Shrimp, Black Worms, and even pieces of raw vegetables work well with betta fish.

Bettas as Pets – Is it a Scammers Stunt?

Betta fish are beautiful, exotic pets. They are very easy to take care of and do not require a lot of maintenance. They are great for beginners who want to try keeping exotic pets. But is it a scam? Yes and no. Betta fish are not illegal to buy or sell in any country. So, you can get them from a reputable breeder or from a pet store (for sale as pets). But these fish are also illegal to transport or sell for food or aquarium use in some countries, and in those countries, these fish are often referred to as “betta fish pets” or “ornamental fish.” So, it’s not a scam, but it is unethical because it is illegal to sell those fish as pets.

Internal Organs and Diabetes Mellitus

Just like humans, betta fish are susceptible to diseases, some of which can cause internal organ damage and even death. One of the most common diseases in betta fish is caused by the protozoa Ich. If your betta fish gets infected with Ich, it will damage its internal organs, causing it to become sick and eventually die. If you notice your betta fish be unhealthy and lethargic, and then it dies, there’s a good chance your betta fish has contracted Ich. Another disease that can affect your betta fish is diabetes mellitus. Like humans, betta fish can develop this disease naturally or from a combination of genetics and poor diet. If your betta fish has developed diabetes, it will be very lethargic. It will lose its appetite and float on the surface of the tank. It is important to treat this disease as soon as you notice symptoms because it can quickly lead to organ failure and death.
