Species Summary

Neon tetras are small freshwater fish native to the Amazon river basin. They can be purchased in quantities of 30, and require specific care such as regular water changes, a pH of 6-7, and a temperature of 72-82°F. Neon tetras are typically gray-silver in color with a glowing red stripe, and can be bought for approximately ₹26 per piece.

When caring for neon tetras, it is important to maintain water quality by performing water changes bi-weekly and using an aquarium water conditioner if required. They also require a balanced diet that consists of small amounts of fish food every week or two. Neon tetra species vary in size, so it’s important to keep them in a tank with other peaceful fish of similar size.

Neon tetra are nocturnal freshwater fish, so they should be kept in an aquarium with dimmer lighting and hiding places. They are fun to watch as they swim gracefully through the tank, darting in and out of the water column with bright neon fins visible in the dark environment. Their friendly personalities make them excellent companions for any aquarium owner.


Neon tetras are popular aquarium fish species that require specific water parameters for breeding. The water temperature should be between 75 and 80 degrees Fahrenheit and a pH level of between 5.0 and 6.0 in order to successfully breed neon tetras in captivity. This can be challenging for aquarists with less experience.

However, experienced aquarists have a better chance at breeding neon tetras than beginners do. Captive breeding is an increasingly popular method of ensuring the survival of neon tetra populations in the wild while still allowing aquarists to enjoy these beautiful fish in their aquariums.


Neon tetras are omnivorous fish that require a balanced diet consisting of live or frozen foods such as bloodworms, brine shrimp, and more to thrive.

They are known for their bright neon-like coloration and are commonly used in freshwater aquariums. These fish are known for their gentle temperament and peaceful behavior in the aquarium.

They are a popular choice for beginner aquarists because of their small size and peaceful nature. However, neon tetras require careful care in order to stay healthy and thriving in an aquarium.

These plants provide hiding places for tetra fish in the aquarium and also help with aqua-toxicity issues. Rocks and driftwood should be placed amongst the plants to create additional areas of refuge.

Neon tetra fish should be kept in an aquarium with similarly non-aggressive tank mates of a similar size to ensure their safety.

These fish are easy to care for when provided with quality food, aquariums with adequate water parameters, and a variety of natural swimming areas.

However, in the absence of aggressive tank mates, tetra fish can become over-stressed and stressed if they are not given adequate space or if they become too comfortable in their aquarium habitat.

Lighting for Neon Tetras

Neon tetras change their colors for camouflage, protection from ultraviolet radiation, and sexual selection through optical interference and chromatophore absorption on their skin cells.

This means that tetra eggs and fry are very sensitive to light, so it is best to keep the tank as dark as possible until the fry are several weeks old.

To ensure the right temperature in tanks for tetras, heaters are needed to maintain the right temperature in the tank. Neon tetras are also vulnerable to temperature swings, so they must be kept at a stable temperature range.

This can be achieved with aquarium heaters or by using an aquarium heater. In addition to this, tetra tanks need low lighting in order to thrive, as bright light can be detrimental to the health of these fish.
