Many fish lovers are looking for a pet fish that is a bit more of a challenge to keep alive. While most pet fish are relatively easy to care for, there are some species that require a bit more maintenance than others. In this article, we will discuss which fish is the hardest to keep alive and why.
When it comes to difficulty, some species of fish are more difficult than others. The most difficult pet fish to keep alive is the Freshwater Eel. This fish is a member of the Gymnotidae family and is native to South American rivers. Freshwater eels are extremely sensitive to water changes and require a very specific habitat. Their tank must be kept clean and free of debris, and the water must be kept at a temperature of around 70 to 85 degrees Fahrenheit.
In addition to the difficult environment, these fish are also hard to feed. They are predatory and require live foods such as worms and crustaceans. They also require a specific diet of vegetables and fruits, which can be difficult to find and provide.
Another difficult pet fish to keep alive is the Discus. This fish is a member of the Cichlidae family and is native to South American rivers. Discus are very sensitive to water changes and must be kept in a very specific environment. They require a tank with a water temperature of around 82 to 88 degrees Fahrenheit, and they should not be kept in an aquarium with other aggressive fish.
Feeding Discus can also be difficult, as they are picky eaters. They need a diet of high-protein foods such as shrimp, small fish, and earthworms. They also require a diet of vegetables and fruits that are specifically tailored to their needs.
Keeping any of these fish alive requires dedication and knowledge of their specific needs. If you are looking for a challenge, these fish are perfect for you. However, if you are new to fish keeping and don’t want to take on the challenge, there are plenty of other species that are easier to care for.
