This peaceful fish is a schooling fish that should be housed in a planted aquarium with plenty of swimming room. To ensure a healthy and stress-free environment for the fish, it is recommended to add a gravel substrate that is dark enough to intensify the fish’s colors. Furthermore, the plants in the aquarium should be chosen carefully to provide sufficient hiding places for the fish. Additionally, regular water changes should be conducted to maintain the water quality and prevent the fish from becoming sick. Overall, providing the right habitat for this fish is essential for its wellbeing.

Melanotaenia lacustris is an egg layer that prefers low to moderate lighting for spawning. It is recommended that spawning take place in the early morning or just after dawn. After hatching, the fry should be fed small live food items such as brine shrimp in order to ensure proper nutrition and growth. Furthermore, it is important to note that the fry will hatch after approximately eight days. With proper care and attention, this species can be successfully bred in captivity.

Turquoise Rainbows are capable of eating a variety of foods, but their diet should consist mostly of prepared flake, frozen, and live foods. Their throats tend to be narrow, so small sized foods are best suited for them.
