The aquarium design is themed around the seasons:

1. Snow-white stones - Winter

Role Design: Represented the cold season, arranging these stones to resemble snowy mountains or ice blocks.

Significance: Added a chilly atmosphere, as if the ecosystem in the tank was in the cold season covered in ice and snow.

2. Wheat-colored stones - Spring

Role Design: Mimicking the rejuvenation of all creatures in spring.

Significance: Brought a lively feeling, symbolizing renewal and hope, injecting vitality into the tank for spring.

3. Mixed black-brown stones - Autumn

Role Design: Created an effect similar to autumn leaves covering the ground, arranged as autumn leaves or a small stream.

Significance: Created a tranquil autumn atmosphere, reflecting the tranquility and maturity of nature in autumn.

4. Gray stones - Rainy Season

Role Design: Formed patterns resembling raindrops or simulated the surface of wet rocks.

Significance: Infused inspiration for the rainy season, conveying the freshness and cleansing of nature during this season.

5. Beige sand - Summer

Role Design: Created beach or desert landscapes under the sunlight.

Significance: Introduced the warmth and relaxation of summer, making the entire aquarium feel like a beach in the scorching summer.

Betta fish (Siamese fighting fish) are a popular freshwater aquarium fish known for their colorful scales, vibrant fins, and aggressive behavior.

Origin:

Betta splendens originated from Southeast Asia, particularly Thailand, Cambodia, Laos and Vietnam

Habitat:

They live in ditches, rice paddies, shallow pools and slow moving streams

Environment:

Freshwater; benthopelagic; pH range: 6.0 - 8.0; dH range: 5 - 19. Tropical; 24°C - 30°C

Physical characteristics:

Betta fish have stunning, colorful fins that flow gracefully. They come in vibrant shades like red, blue, green, and more. These fish can breathe air from the water's surface, thanks to a special organ called the labyrinth.

Biology characteristics:

Feed on zooplankton, mosquito and other insect larvae.

Facultative air-breathing

Bubbles nest builder

Reproduction and mating behavior:

Mating begins with the male Betta building a nest of bubbles. To build this nest, the male swims to the surface, takes a gulp of air and spits out a mucus-coated air bubble

The male very aggressively pursues the female, attempting to entice her under the nest.

After spawning has occured, the bubble-nest then is guarded by male

Taking care of the eggs until the young hatch 24 to 48 hours later,depending upon the water temperature

Cleanse the sand through a series of treatments with chlorine, freshwater, and salt, continuing the process until the water runs clear.

# data[].attributes.body
1. Chlorine Rinse: Place the sand, stones, and pebbles in separate containers and thoroughly rinse each with water containing a small amount of chlorine to disinfect them. Rinse them repeatedly until the water runs clear.

2. Freshwater Rinse: Submerge the sand in freshwater and stir it vigorously to remove residual chlorine. Drain and repeat this process several times until the chlorine smell removed.

3. Saltwater Rinse: Soak the sand in the filtered seawater, stirring to ensure thorough mixing. Saltwater rinsing aids in disinfecting the tank. Saltwater, particularly at specific concentrations, can help kill certain pathogens, bacteria, or parasites that might be present, contributing to a cleaner and safer environment for aquatic life. Rinse the sand with freshwater again to eliminate excess salt until the water becomes clear and free of any debris.

# data[].attributes.body
1. Clear the tank: Empty the tanks by removing all the sand, small stones, and large stones from the previous tank. Then, transfer these materials into the appropriately labeled prepared tank.

2. Filter Cleaning: Remove the filter and gently scrub it using a sponge dipped in a solution of salt and freshwater. Ensure thorough cleaning by scrubbing all surfaces and components of the filter. Rinse it well afterward.

3. Aeration Set Cleaning: Clean the aeration set components by utilizing brushes to scrub the tube. Afterward, replace the existing air pump tubing with new, clear tubing, such as an oxygen soft pump hose or PVC tube.

4. Tank Cleaning: Clean the tank interior by scrubbing its surfaces with a sponge, removing any debris or impurities from the walls, base, and accessories. Start by rinsing with chlorine water, followed by thorough rinses with seawater and freshwater for disinfection before setting it up again.

# data[].attributes.body
1. Decorating: Use the materials prepared, such as pebbles and large rocks, to decorate the interior of the tank. Arrange them creatively to enhance the attractive look of the aquarium.

2. Adding Freshwater: Pour freshwater into the tank, filling it up to approximately two-thirds of the 89 x 42.5 x 46 cm dimensions.

3. Placing Daun Ketapang: Position the daun ketapang (Indian almond leaves) within the tank. These leaves are often used in aquariums for Betta's comfort and enhanced immunity.

4. Activating Aeration: Activate the aeration system to facilitate water circulation and oxygenation, ensuring a conducive environment for the aquatic inhabitants.

5. Ensuring Cleanliness and Water Clarity: Set the aeration to the maximum and then wait for a few days to ensure the sand and other items are thoroughly cleaned, and the water remains clear.

Preparing to Introduce Fish into the Aquarium

# data[].attributes.body
1. Before introducing the fish into the aquarium, I performed several water exchanges. Initially, I placed the fish bags into the aquarium for approximately 30 minutes to balance the water temperature of the fish tank and fish plastic.

2. Then, I used a 20ml syringe to add 10ml of aquarium water into the plastic bag and observed the fish's reactions for about 10 minutes.

3. After that, I removed 15ml of water from the plastic bag and added 20ml of aquarium water, observing the fish's reactions for approximately 10 minutes.

4. Taking out half of the original water from the plastic bag (around 30-40ml), I added 60ml of aquarium water and observed the fish's reactions.

5. After confirming that the fish showed no adverse reactions, I proceeded to introduce them into the tank."

6. No feeding for 1st day of culture as it was adapting to the environment. Hastily feeding can lead to indigestion.

Before engaging in actual breeding, I had two preliminary practical sessions. The first breeding practice took place on Week 2, November 2. I successfully facilitated the mating of male and female fish, resulting in the production of eggs. However, due to my limited experience and the provision of suboptimal food, I fed them algae and artemia cysts, leading to an exceptionally low survival rate. Approximately 96 fry were born, but in the end, only one survived.

The only juvenile that survive through numerous challenges, truly a miracle. Hence, it has been named as Marvel

# data[].attributes.body
The dead fry larvae were further examined under a microscope in the laboratory and no abnormalities were found. It is speculated that their death may be caused by starvation due to improper nutrition.

# data[].attributes.body
The second breeding attempt took place on November 17, 2023. This time, a different diet was introduced, incorporating live feed Artemia, and the survival rate improved significantly compared to the last attempt. However, it is speculated that the transition into the rainy and monsoon periods, coupled with the possible incomplete recovery of broodstock, leads to a significant increase in mortality in the first few days after hatching. Although 81 fry were initially expected, only 21 survived.
