Care and Tank Requirements
Tank Size
Emerald Dwarf Rasboras are small fish, but it’s important to have an appropriately sized tank. For a group of 5-6 individuals, a minimum of 7.5 gallons is recommended. Keep in mind, the larger the tank, the more comfortable your fish will be.
Water Parameters
Emerald Dwarf Rasboras thrive in the following water parameters:
- Water temperature: 72°F to 78°F

Keep a close eye on these parameters, and use an aquarium heater if necessary to maintain the ideal temperature.

- Cryptocoryne
Using a fine sand or gravel substrate will also contribute to their well-being. Add some driftwood and rocks to provide additional hiding spaces and to create a natural look.
Filtration and Aeration
Emerald Dwarf Rasboras are sensitive to water quality changes, so having a good filtration system is essential. Choose a filter with a gentle flow rate to prevent stress on the fish. In addition, an air stone can be added to provide extra aeration and water movement.
Remember, consistent maintenance of your aquarium is essential in keeping your Emerald Dwarf Rasboras healthy and happy. Regular water changes and monitoring of water parameters will ensure a comfortable environment for your fish.
Suitable Tank Mates
When setting up a tank for your Emerald Dwarf Rasboras, you’ll want to consider their compatibility with other tank inhabitants. Since they are peaceful freshwater fish, they get along well with others of the same nature. Avoid introducing large or aggressive fish, as they might target your rasboras as prey and cause stress in the tank.
It is beneficial to choose tank mates similar in size, as they will harmonize well in the aquatic environment. Moreover, selecting fish from the same region as your rasboras, such as Lake Inle, can ensure a more comfortable living arrangement for all.
Here’s a list of suitable tank mates for your Emerald Dwarf Rasboras:
- Sawbwa Barb
- Celestial Pearl Danio
- Glowlight Danio
- Red Dwarf Rasbora
- Small types of catfish
- Dario Hysginon
- Cherry Shrimp
- Most freshwater snails
By carefully selecting the right companions for your rasboras, you can create a diverse and peaceful community aquarium that’s enjoyable for you and your fish.
Breeding Process
To breed Emerald Dwarf Rasboras, start by setting up a separate breeding tank with well-cycled water. Add spawning mops or leafy plants to the tank, as these will provide ideal locations for egg-laying.
Next, introduce a bonded pair or a group of two males and multiple females into the breeding tank. Keep in mind that having more fish may increase the risk of eggs being consumed, so monitor their behavior closely. Feed your breeding group high-protein foods to encourage spawning.
Once females start laying eggs, you’ll notice about 30 eggs throughout the tank. These eggs have a mild adhesive nature, so they might stick to leaves or decor. Be patient, as the eggs will hatch after about 72 hours.
When the fry hatch, they will survive on their egg sac for an additional three to four days before becoming free-swimming. During this time, it’s essential to offer infusoria or powdered fish food until the fry are ready for baby brine shrimp.
By following these steps, you’ll maximize the survival rates of your beautiful Emerald Dwarf Rasbora offspring and enjoy the rewarding process of breeding these colorful, lively fish.
Common Diseases and Treatments
Ich: Ich, or White Spot Disease, is a common ailment in Emerald Dwarf Rasboras. Keep an eye out for white spots on their bodies and fins. To treat it, gradually raise the tank temperature to 82°F and use over-the-counter anti-ich medications.
Fin Rot: Fin rot is caused by bacterial infections, which can lead to frayed or discolored fins. Maintain good water quality and add a fin rot treatment to your aquarium to curb its progression.
Fungal Infections: These can manifest as white, cotton-like growths on your fish. Fungal treatments can be found at most pet stores and are effective in clearing up the infection.
Remember, prevention is key to maintaining the health of your Emerald Dwarf Rasboras. Frequent water changes, proper filtration, and avoiding overcrowding can help minimize the risk of diseases. If you notice any abnormal behaviors or symptoms, act quickly to identify and address the issue.
