Iridescent Shark Species Profile and Identification
The Iridescent Shark, scientifically known as Pangasianodon hypophthalmus, is a member of the Pangasiidae family. Despite its name, it’s not a shark, but a type of catfish native to Southeast Asia.
- Appearance: As juveniles, these fish have a shiny, iridescent color, often grey or black. They’re adorned with two black stripes, one along the lateral line and the other beneath it. This striking look, however, might fade as they mature, adopting a uniform grey.
- Size: They grow big! A full-grown iridescent shark can stretch up to 4 feet (130 cm) in length, and can weigh up to 97 pounds (44 kg). This size requisition makes them unsuitable for small aquariums.
- Lifespan: If cared for properly, Iridescent Shark’s life may span up to 20 years. Their survival, however, largely depends on appropriate tank settings, diet, and overall care.
These fish are also referred to as Sutchi, Iridescent or Shark Catfish, and Swai, a local name derived from Thai language. They’re extensively cultivated in their native habitat, the Mekong and Chao Phraya rivers, not just for their iridescent looks but also as a food source.
Iridescent Shark Supplies
Considering the size and behavior of Iridescent sharks, certain supplies are absolutely vital. Firstly, a big enough tank or pond is non-negotiable.
Iridescent sharks grow very large – up to 4 feet long (1.3 meters). So, a 500-gallon tank is the absolute minimum.
- A small tank inhibits their growth and may lead to health problems in the long run.
Further, a strong filtration system is crucial. These omnivores produce a significant amount of waste. A weak filter system might not be able to handle this. A good filtration system will also ensure high oxygen levels in the water, which is what these river dwellers are used to.
Equally important are tank decorations and hiding places. Moving swiftly, the iridescent shark likes to explore its environment. Places to hide give them a feeling of security.
Lastly, you will require a balanced aquarium diet. Iridescent sharks are omnivores which means:
- They eat both meat, like crustaceans and smaller fish, and plant-based food.
- Commercial pellets or flakes, frozen foods, and occasional fresh greens are a good start.
Evaluate each supply carefully knowing that the health and survival of your iridescent shark depend on a large tank, a powerful filter, hiding spots, and a nutritious diet.
Iridescent Shark Tank Setup
Having chosen to be an iridescent shark owner, the design of your tank is a big deal. Remember, these fish come from the large rivers of Asia. A tank setup mirroring their natural environment is the aim.
Start by getting a large tank, a baseline 500 gallons is crucial. Why? Iridescent sharks can grow up to 4 feet in length (130 cm). Ensure you create plenty of room for them to swim freely.
When it comes to substrate, a mixture of sand and small pebbles works best. This substrate closely mimics the bottom surfaces of their native rivers. For decorations, go for driftwood and sturdy, large plants. However, do not overcrowd the tank, these fish enjoy open swimming areas.
Lighting need not be elaborate, standard aquarium lights work just fine. Iridescent sharks are not specific about their lighting conditions.
Important to note is they are skittish by nature. Sharp, sudden movements can scare them. Prevent injuries by avoiding pointy decorations and ensuring the tank is positioned in a serene area.
Additionally, they prefer relatively dark environments. A shaded corner or room with soft lighting might be the ideal spot for your tank.
Lastly, place your tank in a cool, stable temperature area. Changes in temperature could unsettle your iridescent shark. Always remember, a well-set aquarium guarantees long, healthy lives for your fish.
Iridescent Shark Water Requirements
Maintaining the right water parameters is crucial for the health of your iridescent shark. These fish are naturally found in the warm freshwaters of Southeast Asia, and mimicking these conditions in your aquarium will ensure their well-being.
Start with the water temperature. Iridescent sharks prefer a temperature range of 72-79 degrees Fahrenheit (22-26 degrees Celsius). Use a trusted aquarium heater and thermal thermometer to maintain stable temperatures.
Next, focus on the pH and water hardness. These sharks are comfortable with a pH range of 6.5-7.5, and a water hardness of 2.0-29 dGH. Regularly monitor and adjust these water conditions using reliable testing kits.
To simulate their natural habitat, provide a strong water current in the aquarium. Iridescent sharks originate from large rivers like the Mekong, where waters are deep and currents are fast.
Required water parameters for iridescent sharks:
| Temperature | 72-79°F (22-26°C) |
|---|---|
| pH | 6.5-7.5 |
| dGH (hardness) | 2.0-29 |
| Current | Strong |
Finally, remember to perform water changes regularly to ensure cleanliness. Another crucial step is cycling your tank before introducing the shark, to establish beneficial bacteria that aid in breaking down waste.
Maintaining these water conditions will provide a comfortable aquatic environment for your iridescent shark, promoting good health and longevity.
Iridescent Shark Diet and Feeding
The Iridescent Shark is an omnivore, consuming a broad range of food both in the wild and in captivity. Understanding this dietary profile is crucial for maintaining the healthy growth and well-being of your aquatic pet.
Variety is Key
Feeding time should incorporate a blend of different kinds of plant based and animal based food. These should include:
- Crustaceans
- Smaller fish
- Vegetation
Recreating their natural diet helps ensure the optimal health of your Iridescent Shark.
Feeding Schedule
Feed your fish twice a day, maintaining a consistent schedule. Overfeeding can lead to health issues, hence portion control is essential. Typically, you can use the ‘feed them what they can consume within 5 minutes’ guideline.
Remember, Iridescent Sharks are not just eaters but enthusiasts. They exhibit active pursuit and chase during feeding, proving mealtime to be a stimulating event.
Feeding Mature Fish
Notably, mature Iridescent Sharks’ coloring changes to a more uniform grey, and their dietary requirements alter somewhat too. Frequent meals can lead to obesity in larger, mature Iridescent Sharks. Therefore, you should decrease feeding frequency as your fish ages.
Understanding the dietary needs and feeding behavior of the Iridescent Shark is integral for its proper care. A variety-rich diet, a consistent feeding schedule, and adjustment for mature fish will ensure your shark thrives.
Iridescent Shark Care Schedule
Adopting an Iridescent Shark as a pet can be very rewarding, but it does need a dedicated and regular care schedule. Consistency is key in fostering a stable environment that caters to its unique temperament and sporting habits. Here’s a basic care schedule to help you get started:
- Weekly Tank and Water Maintenance: A weekly 25% water change is recommended to maintain the water quality. Clean the tank regularly to remove any waste or uneaten food. Keeping the tank clean is crucial as dirty water can lead to harmful bacteria which are detrimental to the fish’s health.
- Daily Feeding: The omnivore diet of Iridescent Sharks requires a mix of both meaty foods and vegetables. They should be fed once or twice daily, with only as much food as they can eat in a few minutes to avoid overfeeding.
- Health Check-Up: Inspect your fish daily for any abnormal behavior or signs of illness. Regular vet visits every six months can also be beneficial in maintaining the good health of your fish.
Remember, every fish is unique and so will their specific care needs be. Understanding and adapting to those needs is the key to a thriving Iridescent Shark.
Iridescent Shark Health Problems
Despite their hardiness, Iridescent Sharks are susceptible to several health issues. Often, inadequate husbandry practices are to blame.
Poor Water Quality: Iridescent Sharks need high-quality water to stay healthy. They can fall prey to a variety of skin and fin diseases when water quality is poor. Regular water changes, proper filtration and close monitoring of water parameters are key elements in maintaining their health.
Parasitic Infestations: Iridescent Sharks may become a host for parasites, such as flukes and internal worms. Symptoms include unusual behavior, rapid breathing, and abnormal swimming. Treat your shark promptly to reduce discomfort.
Fin Rot: This is a common problem in many fish and Iridescent Sharks are no exception. It’s caused predominantly by bacteria, and manifests as ragged, decaying fins. Adequate water conditions and a balanced diet can help prevent this issue.
Obesity: One of the major health concerns for Iridescent Sharks is obesity. Overfeeding your Iridescent Shark can result in obesity, which can lead to a plethora of health problems, including swim bladder disorder. Likewise, high fat diets can cause fatty liver disease.

Do remember, prevention is better than cure. A proper diet, along with an ideal living environment and regular vet checkups, can mitigate most health issues before they even start.
Iridescent Shark Tank Mates
Choosing the right tank mates for your iridescent shark is crucial. Not all fish can coexist peacefully in the same aquarium. The following offers useful guidance on this matter.
Size matters: These semi-aggressive fish grow large, up to 4.3 feet (130 cm) and 97 lbs (44 kg). They should cohabit with other larger species to avoid becoming a threat to smaller fish. Fish smaller than the mouth size of an iridescent shark are often seen as food, and not companions.
Understanding temperament: Despite their intimidating name, iridescent sharks possess a semi-aggressive temperament. They form schools, implying that they can get threatened if alone. Fish species like the oscars, larger barbs or large gouramis, which exhibit similar aggression levels, could be your best bet.
Aquatic environment affinity: Preference of water environment plays a key role. Iridescent sharks are freshwater fish with a liking for tropical climate. Fish that share these water preferences make good tank buddies. Match tank mates with similar water parameter requirements – a pH of 6.5–7.5, hardness of 2.0–29 dGH, and 72–79 °F (22–26 °C).
Adherence to these guidelines will foster a compatible, delightful ecosystem. The crucial thing is to ensure the set-up allows cohabitation instead of competition. This will provide an enjoyable fishkeeping experience.
Iridescent Shark Breeding
Breeding Iridescent sharks in captivity is a complex process and generally not recommended for beginners. Professional breeders often undertake this task, due to the size of the fish and the specific conditions required.
Here’s what you need to know, although it’s advisable to gain more experience in fishkeeping before embarking on this venture.
Maturity: Iridescent Sharks reach sexual maturity around the age of 2 years. Males develop a thicker, pointed anal fin and females exhibit fuller bodies when ready to breed.
Spawning: In their natural habitat, they typically breed in floodplains during the rainy season. Replicating these conditions with a significant increase in water volume could trigger spawning.
Eggs and Fry: The female scatters the eggs which stick to plants and other objects. If successful, the fry hatch in about 24 hours. Unfortunately, parent sharks often eat their young, so immediate removal of fry is critical.
Raising Fry: The newly hatched fry should be kept in a separate tank and fed a diet of infusoria and brine shrimp.
Remember, breeding these large and complex creatures is complicated – it requires a deep understanding of their needs and a significant time commitment. Despite difficulties, successfully breeding Iridescent Sharks can be a rewarding experience for the advanced aquarist.
