One possibility is that your shark is sick or injured. In this case, you should contact a veterinarian who specializes in fish. Another possibility is that your shark is tired. If this is the case, you can try to get him to swim by giving more light or adding some live food to the aquarium.
They require a balanced diet but will eat a variety of live, frozen or pellet/flake foods. For a balanced diet feed your iridescent catfish two to three times a day high-quality flakes. Be careful not to overfeed them by feeding them just enough food for them to eat it all in about 5 minutes.
Nonetheless they are always on every list of aquarium-friendly freshwater sharks. What is that? You can find iridescent sharks scattered throughout Southeast Asia. They are tropical freshwater fish that tend to stay on deep and wide rivers where they have enough room to roam freely.
They are freshwater fish that originally live in a tropical climate and prefer water with a pH of 6.5-7.5, a water hardness of 2.0-29 dGH and a temperature range of 22-26 ° C (72-79°F).
Perhaps your fish has just become fussy and tired of eating the same food every day. Along with the branded food you feed your fish, try feeding them a variety of live foods. If they still don’t eat, don’t leave it for too long. Call the fish vet.
Stress. Stress can sometimes cause a fish not to eat. Stress can occur when a fish is moved from one tank to another for cleaning or transfer, or when there is a sudden change in tank temperature. Marine fish are more susceptible to temperature-related stress than freshwater fish.
Do iridescent sharks play dead? Sometimes, especially when scared, this fish may choose to play dead. If your fish swims in the water, before you take it out of the water, double check that it’s not just faking it.
Interestingly, juvenile iridescent sharks have teeth. These teeth are used to cut and tear meatier foods while young. As they grow to their adult size, they lose these teeth and tend to prefer more plant-based foods and prey that they can swallow whole.
The impaired buoyancy in fish is caused by a malfunction in their swim bladder. When fish are affected by a swim bladder disorder, they often lose the ability to swim properly. They will float uncontrollably to the top of the aquarium, upside down, while still alive.
They are diurnal in their habits. Even when the rainy season clouds the water, these barbels give them a chance to “see” around them. You’ll find them listed under a variety of common names: iridescent shark, iridescent catfish, sutchi catfish, Siamese shark, or (if you’re looking for a menu) swai.
Although they do not bite goldfish, they are actually members of the catfish family and are very shy by nature. As soon as there is sudden movement, they start running around the tank, often causing injury to themselves and others.
– Growth Rate
Most iridescent sharks are around 5 to 10 cm when purchased. Their growth rate is actually very fast compared to most other fish, especially if you give them a huge tank and a meaty diet full of proteins. If so, you’ll see them grow to about a foot.
within a year
Iridescent sharks can live for 15 to 20 years in captivity, but the sad truth is that the majority of young fish survive only a few years due to inadequate conditions. Cramped tanks, aggressive tank mates, dirty water and poor diet all take their toll on these delicate catfish and shorten their lifespan.
During the spring or summer months, keep an eye out for signs of females carrying eggs once they are fully grown. Males fertilize the eggs that the females lay. Watch your pond to see if small, young iridescent sharks have appeared, which means your fish have successfully spawned.
Most sharks are omnivores in captivity and thrive on a varied diet that includes Aqueon Tropical Flakes, Color Flakes, Spirulina Flakes, Tropical Granules, Algae Rounds, Bottom Feeder Tablets, and Shrimp Pellets. Frozen and live foods can also be fed as treats to enhance growth and colour.
Many fish swallow their food whole, which means they can’t break down large flakes or pellets that won’t fit in their mouths. If the food you are giving your fish is untouched or looks larger than your fish’s mouth, chop it up before feeding or find a smaller food.
