Sharks are one of the most fascinating and feared creatures in the ocean. However, there are fish that, although they include the word "shark" in their name, do not pose any danger to humans. Among them, the redtip shark, a calm and peaceful species, although under certain circumstances it can become a bit territorial. This species, scientifically known as Epalzeorhynchos frenatum, is native to Southeast Asia, like its "close relative", the red-tailed black shark (Bicolor Labeo).
Main characteristics of the redtip shark
El redtip shark It stands out for its thin and elongated body, generally reaching 15 centimeters in length in aquariums, although in exceptional cases it can reach up to 18 centimetersTheir bodies are usually bright silvery in color, making them stand out in aquariums that are well decorated with plants and rocks. Their most distinctive feature is, as their name suggests, the red color of their caudal fin, which contrasts with the rest of their body.
These fish are extremely active, so they need an environment that allows them to swim freely. It is recommended to keep them in aquariums spacious and well equipped, with hiding places and areas of vegetation where they can rest.
Optimal aquarium conditions
If you are considering adding a redfin shark to your aquarium, you should pay special attention to the water conditions. To ensure the well-being of these fish, follow these recommendations:
- Water temperature: Keep the water at a constant temperature of between 22 ° C and 26 ° CBeing 24 ° C the ideal.
- pH: The pH range should be between 6.5 and 7.5, with a slightly neutral acidity.
- Water hardness: The hardness should range between 9th and 16th, semi-hard to moderately hard.
- Aquarium size: A tank of at least 150 liters is essential for a single copy.
In addition, it is recommended to include natural plants, logs, rocks and other decorative elements that not only beautify the aquarium, but also provide essential hiding places to reduce stress and help delimit territories.
Redtip shark feeding
The redtip shark is a omnivore, which means that their diet can include both animal and plant-based foods. However, to maintain their health and vibrant coloring, it is essential to provide them with a varied and balanced diet.
Among the most suitable foods are:
- Live foods: They love earthworms, brine shrimp, tubifex and mosquito larvae. These foods are not only nutritious, but also stimulate their natural hunting instincts.
- Plant foods: Fresh vegetables such as spinach, lettuce or zucchini can be offered. Seaweed is also an excellent option.
- Commercial foods: They readily consume pellets, flakes and other products designed for aquarium fish. Make sure they contain Spirulina or other herbal supplements.
It is important to control portions and avoid overfeeding, as this can lead to health problems such as obesity or water pollution.
Behavior and sociability
Despite its peaceful appearance, the redtip shark can become territorial under certain circumstances, especially if it feels uncomfortable or stressed. For this reason, it is best to keep them as solitary fish or in the company of compatible species. Avoid including smaller or shy fish, as they may become targets of hostility.
Among the best species to live with the redtip shark are the barbos, botias and fish of similar size. On the other hand, it is not advisable to keep them with other redfin sharks, unless they have a large tank with multiple hiding places that minimize visual contact between them.
Reproduction in captivity
The reproduction of the redtip shark in captivity is extremely difficult and has rarely been successfully achieved. When it does occur, it is usually due to the application of advanced techniques, such as hormone injection derived from the carp pituitary gland.
The reproductive process includes:
- Bridal stop: During courtship, males and females perform characteristic movements before spawning.
- Spawning: The female can deposit up to 1000 eggs in places with strong currents. The eggs must be kept in constant movement, since if they fall to the bottom of the tank they can become infected and not develop properly.
Once the fry are born, they are pale blue in colour and begin to develop the characteristic colouring over time. During the first few weeks, they should be fed with brine shrimp nauplii and then with crushed vegetable foods.
Other species of "shark fish"
The term "shark" in aquarium hobby is not limited only to the red-tip shark. There are other species that share this name due to their body shape or fins similar to those of marine sharks:
- Angel shark: It lives on the seabed and only becomes aggressive if it feels its life is in danger.
