The Amazing World of Captive Ornamental Fish Breeding
Captive breeding of species such as Pterapogon kauderni, commonly known as the Banggai cardinalfish, is an emblematic example of how human intervention can have a positive impact on species conservation. Once on the verge of extinction due to overexploitation, today it flourishes thanks to captive breeding techniques that not only ensure its survival but also protect its natural habitat.
However, raising ornamental fish is not without its challenges. Breeding species such as the betta and the dancer requires in-depth knowledge and dedication that goes beyond the hobby. It is an art that combines science with patience, where each new birth is a triumph against adversity.
Some examples of fish species that are known to be easier to raise in aquariums:
- Guppy (Poecilia reticulata): They are ovoviviparous, very resistant and prolific. They are easy to reproduce and are ideal for beginners.
- Goldfish (Carassius auratus): It is one of the most popular and easiest fish to raise in home aquariums.
- Cherry Barbel (Puntius titteya): Also ovoviviparous, it is so prolific that it can reproduce almost every three weeks.
- Dwarf cichlids (Apistogramma spp.): They are a large family of freshwater fish that can be raised relatively easily in the aquarium.
- Betta Fish (Betta splendens): Although they require some specific care, bettas are vibrantly colored fish that can be raised in small aquariums.
Beyond beauty and conservation, raising ornamental fish in captivity represents a significant economic opportunity. In countries like Colombia, the exploitation of the Amazonian arawana in captivity has proven to be a profitable business for fish farmers, providing sustenance and prosperity to entire communities.
Some useful advice in the form of tips for breeding ornamental fish:
- Keep your aquarium clean: Perform frequent water changes to keep the water fresh and healthy.
- Quality food: Use good quality food to ensure adequate nutrition.
- Control the pH of the water: It is vital for the health of the fish to maintain the pH of the water within the appropriate ranges.
- Avoid overpopulation: Too many fish can cause stress and illness.
- Set a light schedule: This helps simulate a natural day and night cycle.
- Provide hiding places: Fish need places to hide and feel safe.
- Buy healthy fish: Make sure the fish you buy are disease-free.
The lifespan of ornamental fish varies depending on the species, but here are some general examples:
- Goldfish (Carassius auratus): They can live 10 to 15 years in a suitable aquarium.
- Guppies (Poecilia reticulata): Their life expectancy can vary from 1 to 3 years.
- Scalars (Pterophyllum): They can live 8 to 10 years in captivity1.
- Nun Fish (Gymnocorymbus ternetzi): They can live between 3 and 5 years, depending on the environment and their diet.
Breeding ornamental fish in captivity is more than a hobby; It is a fusion of art, science and sustainability. With every fish born in captivity, we take a step toward a future where the beauty of nature and the well-being of our planet coexist in harmony.
