Behavior And Temperament
Like the other species in the Rasbora family, the Emerald Eye is a very peaceful and friendly fish.
It can live in harmony with various fish species as long as they don’t bully your Emerald Eye Rasbora.
Besides their friendly and non-aggressive nature, the Emerald Eye fish loved swimming around and staying active all day.
Some individuals are pretty shy, while others are very sociable.
The Emerald Rasbora also loves swimming and living in groups with the other Rasbora in the wild.
It increases their chance of survival and helps the fish gain more confidence.
Therefore, you should keep the Emerald Eye in large stocks (at least six) to increase the aesthetic aspect of the aquarium tank.
Regarding the swimming pattern, this fish’s favorite territory is the mid to upper levels of the tank.
Despite their peaceful nature, the Emerald Eye Rasbora can sometimes get in conflict with the other fish in extreme conditions.
Therefore, setting up suitable and ideal water parameters for the Emerald Eye is advisable.
When the breeding seasoning comes, the male Rasboras will perform special swimming patterns and lurk around the female ones to display their beautiful colors.
It helps attract the female fish and prepare for the upcoming breed.

Basically, you can put Emerald Rasbora with any type of small and peaceful fish, especially the species belonging to the Rasbora family.

Diet And Feeding
Since the Emerald Rasbora fish are omnivores, you should not choose a squeamish diet for them.
The Emerald Eye can consume a variety of food, including both plant-based and live food sources.
In the wild, this species can eat any food it finds consumable, ranging from plants, insects, and crustaceans to crustaceans.
Similarly, you can recreate this feeding diet to enhance the fish’s growth and well-being.
Micro pellets and crushed flakes balance the Emerald Eye diet and supply them with more fiber and vitamins (nutrients from plant-based food sources). It’s essential to diversify the Emerald Rasbora diets.
Regarding the live food sources, the mini-bloodworms can supply the Eye Rasbora with protein and essential nutrients.
Feeding the fish bloodworms can significantly enhance their growth in the maturing phase.
If you can’t find the mini bloodworms, consider using mosquito larvae as an alternative option. Ensure to choose white larvae that are safe for fish consumption.
I also feed my Emerald Eye Rasbora and the other small fish with Cyclops fish food.
This product contains tiny, fresh, and frozen zooplankton that can supply the pet fish with valuable nutrients and energy.
Another excellent food choice is the Daphnia, which is a small-sized crustacean.
Daphnia features many valuable nutrients found in natural algae, and they can be fed to fish frozen or fresh.
Breeding
The Emerald Eye Rasbora can constantly produce eggs and scatter the eggs in many places in the tank.
A mature Emerald Rasbora can produce and scatter a few eggs per day, and you can see them lying on the decorations and plants.
However, the large Emerald Eye Rasbora and other fish species may mistake the eggs for food due to their tiny size.
Therefore, the chance of the eggs getting eaten by mature fish is very high.
You can set up more plants and some ideal hiding spots for the eggs. Covering the offspring will allow them time to grow and hatch into fish without getting eaten by the other fish.
You can also separate the breeding Emerald Rasbora into another tank and play the mesh barriers on the tank substrate.
The eggs will fall onto these warriors, preventing them from sinking deep into the substrate.
In addition, raise the tank temperature and pH levels a little higher than in the regular environment.
Remember to feed the breeding Rasbora with live bloodworms or frozen food frequently throughout the day.
The Emerald Eye’s eggs only take a few days to hatch and reach around 3 to 4 millimeters in length.
When the baby fish hatches, you can feed them with Paramecium or small shrimp to enhance their growth.
Tank Requirements
The living environment of the Emerald Eye Rasbora must always be fresh water because the fish can only thrive in this condition.
You can freely choose the tank size depending on the fish’s amount, but it should exceed 10 gallons.
The ideal temperature range for Emerald Rasbora is between 68 and 77ºF.
Meanwhile, the tank substrate should be filled with dark-colored sand because the fish love soft surfaces.
You should set up a lot of decorative elements and plants in the tank, such as thick vegetation and floating algae.
The ideal water hardness and pH level are 2-12 and 5-7,5 pH, respectively.
Common Diseases
The Emerald Rasbora fish are very hardy, and they are rarely infected with diseases or bacterial infections.
However, you should be careful of common diseases like fin rot, Columnaris, or Ich.
How To Care For Emerald Eye Rasbora?

Despite their tiny sizes, the Rasbora needs to be fed daily, divided into many times a day.
Also, don’t forget to install a high-quality tank filter and oxygen provider if you raise large stocks of Emerald Rasbora fish.
