The larger the tank, the better due to the amount of waste they create. These recommendations are for one fish only. They will show different temperaments during different life stages. So, even if they are good community fish when they are juveniles they can become very aggressive during adulthood. These fish are not for community aquariums and are best kept alone. They are veracious fin nippers and get bored quite easily, a combination that can result in a catastrophe if paired with other fish.
However, there are a few species that can be kept as a pair or small groups. Figure 8, South American, and the Ceylon puffer can all be kept in small groups. Freshwater puffer fish do not have any scales so they are very susceptible to ectoparasites. The most common parasites are usually caused by Protozoa living in their gills, fins, and skin. The most common parasites are known as Oodinium sp. One of the most common parasites among ornamental freshwater fish is known as the Ich disease caused by Ichthyophthirius multifiliis.
This can be treated quite easily by raising the temperature of your aquarium. Preventing the disease is always better. New additions to your aquarium are potential carriers of disease and bacteria. Try to be careful when introducing new things to your aquarium and make sure to quarantine them.
Scaleless fish, like Puffers, are particularly susceptible to diseases because they lack the first line of defense, scales. It is very important that you are very careful in maintaining the right water conditions and keeping your tank clean.
In their natural habitats they tend to eat snails, crustaceans, shellfish, and other fish yes, even whole fish. They will eat pretty much anything you put in the tank. You can feed them live, frozen and dried meat. Bigger size puffers can eat small frozen fish such as lancetfish or whitebait fish.
Their teeth are an important aspect to consider as they keep growing during their whole life. You might need to feed them hard substrate animals such as shellfish, crustaceans, or snails to help them control their teeth growth. Try to not overfeed them; they are very good at earning more food by doing things to try and impress you such as squirting water at the top of the tank.
Breeding puffers in captivity is very difficult. Different species require different water parameters and conditions. Generally, puffer fish are extremely protective of their eggs however when hatched the parents will probably eat them.
Providing enough food for the fry is very difficult and they are very sensitive to water quality. You can feed them brine shrimp and infusoria. As all of these challenges make breeding these fish and raising their fry incredibly difficult but very rewarding. Puffer fish are found across tropical water bodies, from freshwater to marine environments. There are at least 30 species of freshwater puffer fish around the world, all different in sizes and colors.
They are well known for their ability to puff up as a defense mechanism, a characteristic which they have evolved to protect themselves. These fish are recommended for experienced aquarists due to their special feeding needs and sensitivity to water conditions.
Even though their temperament is aggressive, they are very intelligent and will soon grow to recognize you, especially during feeding times. I have been able to identify my fish as female. Even with proper preparation by a trained chef, about a half dozen diners die every year from the paralyzing effects of eating puffer fish, so they should generally not be considered food.
Despite using their fins to help them swim with a tail fin acting as a rudder , puffer fish are notoriously slow-moving. However, they do have other methods for deterring—or defeating—predators out to get them, said Claricoates, including:. Puffer fish do not have scales, but instead have spines which you may not be able to get a good look at until they puff up , said Claricoates. As a fish owner, you have to be sure that the water quality is excellent—specifically nitrite, nitrate and ammonia levels in your tank.
If these levels are high, it often indicates a dirty tank, and can create health issues for your fish, she said. Water checks can be done by fish stores for you on a monthly basis or you can purchase a home kit to test your water, she said. A puffer fish, if kept in an ideal environment, can live up to ten years. In the wild, puffer fish are predators, and eat a variety of snails, shellfish, crustaceans and other fish, said Claricoates.
In captivity, puffers will eat almost anything, so a variety of foods should be offered to allow for a healthy mix, she said. Claricoates recommends a diet consisting of foods with shells, including blue crab, mussels, clams, shrimp, live snails and bloodworms. She also advised that when or if you are offering live food, it must be quarantined in a separate aquarium for a month prior to feeding it to your puffer fish.
This ensures the food is healthy and prevents puffer illness from unhealthy food. Many fish species have teeth that stop growing at some point, but puffer fish do not.
Because they eat hard foods, they have teeth also called beaks that continuously grow throughout their lives, said Claricoates. This makes it paramount to offer your puffer fish food with hard shells to help organically trim their teeth. Without snails or the like, your puffer fish may require veterinary dental attention. How much you feed your puffer fish—and what is left over—will cause elevations of the nitrates and nitrites in your tank.
In Japan , they are called fugu and are a very expensive, delicious treat. They are prepared only by trained, licensed fugu chefs. Most puffers are found in tropical and subtropical ocean waters, but some species live in brackish and even fresh water.
Some species of pufferfish are considered vulnerable due to pollution, habitat loss, and overfishing, but most populations are considered stable.
