About Carangidae fish
The Carangidae fish are in the order Perciformes, and are commonly known as jacks, pompanos, trevallies, and scads (from wikipedia.org). It is a diverse group of marine fish that belong to the family Carangidae.
They are found throughout the world, ranging from coastal waters to the deeper sections of the ocean. Some species also venture into brackish and even fresh waters. For example, the Bigeye Crevalle Jack (Caranx sexfasciatus), is sometimes encountered in brackish estuaries or in freshwater.
They are known for their fast swimming abilities and are often highly migratory. Carangidae fish are typically found in warm coastal and offshore waters around the world. Some species are solitary, while others form schools or shoals.
The minimum lighting illumination range for fish is below 10–2 lux. Fish with strong phototaxis are also the species with strong aggregation, including Carangidae fish.
Carangidae species are recognized for their streamlined, powerful bodies and their ability to swim fast. Many of them are known for their sporting.
Carangidae fish characters
Here are a few key characteristics of the Carangidae fish:
Size: Carangidae fish vary greatly in size, with some species growing quite large, reaching lengths of several feet or growing up to 1 meter in length, while others remain small measuring only a few inches in length throughout their lives.
Shape: They have a variety of body shapes, ranging from slender to more robust forms. They typically have a thin, deep body that’s much narrower from the side view compared to the top view, which is well-suited for fast swimming in open waters and making them highly aerodynamic swimmers.
Coloration: Many Carangidae are silver or gray which helps them blend into their surroundings, although some species may have yellow, green, and blue hues, or have distinct patterns or markings on their bodies. Interestingly, the coloration can also change according to the fish’s environment or mood.
Diet: Carangidae fish are opportunistic predators and use their speed and agility to chase and capture prey. They are carnivorous, a variety of smaller fish, crustaceans, cephalopods, and plankton are all in their diet sheet.
Fins: Most of the Carangidae fish have two dorsal fins, with the first dorsal fin usually having spines. The anal fin is generally long and extends almost the entire length of the body. The tail fin can aid in their swimming abilities by being deeply forked.
Mouth and Teeth: Most Carangidae fish have a protracting mouth, which means their mouth can extend forward to capture prey. They typically have sharp teeth, including canines, that are adapted for capturing and holding onto their prey.
Reproduction: Carangidae are usually pelagic spawners, releasing their eggs into the water column where they are fertilized and then float freely.
Brackish Carangidae fish
Many Carangidae species are important for commercial fisheries and are also popular among recreational anglers. Some of the most popular species include Yellowtail, Giant Trevally, and the various types of Pompano.
It’s important to note that the Carangidae family is quite diverse, with numerous species exhibiting variations in these characteristics. Therefore, specific features and behaviors may vary among different species within the family. Now, do you know the name of the Carangidae fish that have 8 dorsal fins and swim like fireworks in the blackwater?

Maintaining a healthy environment for your aquatic pets is essential to their well-being and longevity. In an aquarium that is not properly established or maintained, ammonia can accumulate and reach harmful levels for fish.
Ammonia in fish tank
Ammonia is a toxic substance that released by fish waste and decaying matter, it can be detrimental to the health of fish.The main sources of ammonia are fish waste, uneaten food, and decaying organic matter such as dead plants or fish. Ammonia is produced through the breakdown of these organic substances by bacteria.
In a healthy aquarium, beneficial bacteria called nitrifying bacteria convert the toxic ammonia into less harmful substances, it through a process known as the nitrogen cycle. Initially, ammonia is converted into nitrite (NO2-) by bacteria called Nitrosomonas. But Nitrite is still toxic to fish, so another group of bacteria called Nitrobacter convert it into nitrate (NO3-), which is less harmful to fish in low to moderate concentrations. Nitrate can be removed from the water through regular water changes or live plants that can use it as a nutrient.
What causes ammonia in fish tank
Ammonia spike can happen due to various reasons below:
Overstocking: Having too many fish can overload the biological filtration capacity, leading to excess ammonia production in the tank.
Overfeeding: Feeding fish more than they can consume within a few minutes can result in uneaten food sinking to the bottom and decomposing, releasing ammonia into the water.
Poor filtration: If the aquarium filter is not properly sized or functioning, it may not be able to handle the biological load, allowing ammonia to accumulate to a spike.
Lack of maintenance: Infrequent water changes or failure to remove decaying organic matter can lead to ammonia build-up.
New tank syndrome: When setting up a new aquarium, the beneficial bacteria that convert ammonia to nitrite and nitrate need time to establish. During this initial phase, ammonia levels may rise until the bacterial colonies have grown sufficiently.
Fix ammonia in a fish tank
Now, let’s explore effective strategies to reduce high ammonia levels in fish tank, and promote a safe and thriving habitat for your underwater world.
Regular water changes
One of the simplest yet most effective ways to reduce high ammonia levels in tank is through water changes.
Aim to change approximately 25% of the tank water every one to two weeks, depending on the size and stocking level of your aquarium. Use a siphon or a gravel vacuum to remove any uneaten food, fish waste, and debris. Then, replace the removed water with dechlorinated water that matches the temperature and pH of the tank.
Make a feeding schedule
Overfeeding your fish can lead to excessive ammonia production, so it is crucial to feed your fish the appropriate amount of food, ensuring they consume everything within 2-3minutes. The uneaten food will decompose and contribute to ammonia levels.You should consider a feeding schedule that involves small, frequent meals rather than a single large feeding. This approach minimizes leftover food and reduces the potential for ammonia spikes.
Install a quality filter
An aquarium filter is essential for maintaining water quality in your fish tank. Ammonia is converted into less harmful substances through the nitrogen cycle, primarily performed by beneficial bacteria residing in the filter media. Ensure that the hygger filter is properly sized for your tank and it is clean and replaced regularly. If necessary, consider upgrading to a more efficient filter that provides adequate mechanical, chemical, and biological filtration.
Establish a balanced Bioload
The bioload refers to the total amount of waste produced by the fish and other inhabitants in the tank. Overstocking can overwhelm the biological filtration capacity of your aquarium, leading to increased ammonia levels. Ensure your tank size and filtration system can accommodate them appropriately. It is better to under stock your tank and provide a healthier environment for your fish.
Introduce live plants
Aquatic plants offer numerous benefits.Consider adding live plants to your aquarium to help reduce ammonia levels. Plants also provide additional oxygen, shelter, and aesthetic appeal to your tank.
Test and monitor Ammonia levels
Monitoring ammonia levels in the tank is crucial to ensure the health of the fish. Regularly test in your aquarium using water testing kit allows you to identify any fluctuations or Ammonia spikes promptly. Maintain ammonia levels below 0.25 ppm, as even low concentrations can stress fish and compromise their immune systems. Monitoring ammonia levels will help you take immediate action and prevent any long-term negative effects on your fish.
By following these strategies, you can effectively reduce high ammonia levels in fish tank, and provide a healthier and safer environment for the aquatic pets. The prevention is the key, so maintaining good water quality through regular maintenance practices is vital.
