Are dwarf puffer fish easy to keep
Are puffer fish hard to keep? Not absolutely, it varies from different fish types. Generally, dwarf puffer fish are easy to maintain. For how to care for freshwater puffer fish, you should make sure of a comfortable living environment, a proper diet, suitable tank mates, and something like that.
In general, a large fish tank is better. It can reduce the risk of water parameter fluctuation and provide sufficient space for fish to swim and explore. Likewise, puffer fish are sensitive to water conditions. Accordingly, you can add an aquarium filter to keep clean water. Also, an aquarium heater would be helpful to maintain a stable water temperature.
Usually, the water temperature in freshwater puffer fish aquariums should be kept between 74℉ and 78℉. Besides that, puffer fish need hiding places. Hence, you can decorate the fish tank with some aquarium decorations, like caves, rocks, hollow tree trunks, and plants.
In addition to the living environment, puffer fish compatibility should be considered. Some freshwater puffer fish would nip other fish’s fins, while some are aggressive. Take dwarf puffer fish as an example, they are small but aggressive. However, though it is better to keep them alone, you can hold them with fast-moving fish, such as danios. On the other side, some must be kept single in a tank, such as Mbu puffer fish, Mekong puffer fish, and Nile puffer fish. In a word, you should be cautious when introducing tank mates to puffer fish aquariums.
What do puffer fish eat?
What do puffer fish eat? It depends on the fish types. Some are piscivores, like Congo puffer. And some are carnivores, for instance, the Red-eye puffer. At the same time, there are omnivores, golden puffers for example. Nonetheless, no matter what you feed, you should ensure a proper and balanced diet. In addition to meat, you can provide some vegetables from time to time.
For instance, once or twice each week. Aside from that, puffer fish’ teeth would not stop growing. It means that their teeth will keep growing as they get older. As a result, you should give them food with a rigid substrate, which could limit the teeth’ growth. Snails, crustaceans, or shellfish are great alternatives. Nevertheless, if the teeth are too long, you can clip them.
