Betta Imbellis Care And Set Up Tips

From the shimmering tank to the colorful decorations, there’s a whole array of equipment waiting to make your Betta imbellis feel like a superstar.

So, get ready to create a cozy and captivating environment that will have your fish swimming with joy. Let’s explore the must-have gear, from filters to heaters, that will make your Betta imbellis feel right at home. Get your fins ready, because it’s time to embark on an aquatic adventure like no other!

To provide proper care for your Betta imbellis as a pet, you will need the following equipment:

Aquarium Tank

Choose a tank with a capacity of at least 5 gallons to provide enough space for your Betta Imbellis to swim and explore. Opt for a tank made of glass or acrylic, as they are easy to clean and maintain.


Install a gentle and adjustable filter to maintain water quality and remove impurities. A sponge filter or a small hang-on-back filter with adjustable flow rate is recommended. Ensure that the filter does not create strong currents that can stress your Betta Imbellis.


Betta Imbellis is a tropical fish that requires a stable water temperature between 75-80°F (24-27°C). Use a reliable aquarium heater with a built-in thermostat to maintain the desired temperature range.


Place a thermometer inside the tank to monitor the water temperature regularly. This will help you ensure that the water remains within the optimal range for your Betta imbellis.


Provide adequate lighting for the tank, either through natural sunlight or by using a low-intensity aquarium light. Aim for a regular day-night cycle, providing around 8-12 hours of light each day.


Choose a soft substrate like fine gravel or sand for the tank bottom. Avoid using sharp or rough materials that can injure your Betta Imbellis delicate fins. A substrate also provides a natural-looking environment for your fish.


Add betta-friendly decorations to the tank, such as silk, floating, and live plants, caves, and driftwood. These provide hiding spots and resting places for your Betta Imbellis, creating a more stimulating and natural habitat.

Water Conditioner

Treat tap water with a water conditioner specifically designed for aquarium use. This helps remove harmful chemicals like chlorine and chloramine, making the water safe for your Betta imbellis.

Fish Food

Feed your Betta Imbellis a balanced diet of high-quality betta-specific pellets or flakes. Look for food that is rich in protein and includes a variety of nutrients to support their health and vitality. Supplement their diet with occasional treats like freeze-dried or live foods.

Fish Net

Keep a gentle fish net on hand to safely handle and transfer your Betta imbellis when necessary, such as during tank maintenance or when introducing them to a new environment.

Remember to regularly monitor the water parameters, perform routine water changes, and provide a stimulating and enriching environment for your Betta imbellis to thrive.

Food and Diet

Betta imbellis are carnivorous fish and thrive on a diet of live or frozen foods. Suitable options include brine shrimp, daphnia, bloodworms, and mosquito larvae. High-quality betta pellets or flakes can also be included. Feed small portions multiple times a day to prevent overfeeding.

Live Foods

Live foods like baby brine shrimp, daphnia, and mosquito larvae are highly nutritious and mimic the natural diet of betta imbellis in the wild. These live organisms provide essential proteins and vitamins, promoting healthy growth and coloration. You can find live foods at local fish stores or breed them at home using culture kits.

Frozen Foods

Frozen foods such as bloodworms, brine shrimp, and daphnia are convenient alternatives to live foods. They retain much of the nutritional value and are easily accessible at pet stores. Thaw the frozen food before feeding it to your betta imbellis to ensure they can consume it comfortably.

High-Quality Betta Pellets

Betta pellets are specially formulated to meet the nutritional needs of bettas, including betta imbellis. Look for high-quality pellets that are rich in protein and contain essential vitamins and minerals. Ensure that the pellets are of an appropriate size for your betta imbellis to eat comfortably.

Betta Flakes

Betta flakes are another option for feeding betta imbellis. Look for flakes specifically designed for carnivorous fish, as they provide a balanced diet containing proteins, vitamins, and minerals. However, flakes may be less preferred by betta imbellis compared to live or frozen foods.

Remember to vary your betta imbellis’ diet and offer a mix of different food types to ensure they receive a well-rounded and nutritionally balanced diet. Feeding a variety of foods will also help stimulate their natural hunting instincts and provide enrichment. Monitor your betta imbellis’ feeding habits and adjust the quantity of food based on their appetite and condition.
