Regular water changes and proper maintenance are vital for their optimal behaviour and breeding success.

Sexual Dimorphism

Male and female Loreto Tetras display varying physical characteristics, a phenomenon known as sexual dimorphism. Males are typically more brightly colored and have longer fins than females. This distinction makes it easier to identify the sexes, which is essential for successful breeding in captivity. Providing a separate breeding tank with hiding places and optimal water conditions can encourage spawning and ensure the overall health of your Loreto Tetras.


Breeding Loreto Tetras requires careful planning and preparation. It’s important to provide them with plenty of hiding places and plants to lay their eggs on, as they are egg-layers and will scatter their eggs on surfaces in the aquarium.
