Reproduction of fish in the aquarium
Breeding fish in captivity is one of the most rewarding challenges. Each species has specific requirements for spawning and fry rearing.
Detailed explanation
Reproduction varies enormously from species to species. Livebearers (guppies, platies, mollies) give birth to already formed fry. Oviparous birds require more precise conditions.
Substrate oviparians (dwarf cichlids, Apistogramma) lay their eggs on a surface and actively care for them.
Bubble nest builders (Betta, Gourami) build a nest where they lay their eggs. The male defends them.
Feeding the fry is the biggest challenge. Infusoria, Artemia nauplii, microworms are the foods for the first few days.
The breeding aquarium should be separated from the display. Genetic selection is a fascinating aspect that requires knowledge of genetics and many aquariums.
