Setting up a proper aquarium for betta fish requires comprehensive consideration of size, material, landscaping, and functional configurations. Here’s a step-by-step guide with key precautions:
I. Aquarium Selection and Size
Minimum Size Requirements
A 20×20×20cm ultra-clear square tank (holding approximately 8 liters of water) is recommended. The absolute minimum should not be smaller than 15×15×20cm (4.5 liters).
Round or irregularly shaped tanks can distort light refraction, damaging bettas’ eyesight.
Material Recommendations
Ultra-clear glass tanks are preferred for their excellent transparency and aesthetic appeal.
Acrylic tanks are lightweight and easy to customize but require careful handling to avoid scratches.
II. Aquarium Setup and Filtration System
DIY Aquarium Tutorial
Cut tiles (1cm thick) and glass using a glass cutter, then assemble them according to the desired dimensions (e.g., a 20×20cm tank body).
Use glass glue to bond the pieces, ensuring edges align properly to prevent leaks.
Filtration Configuration
Bettas are sensitive to strong water flow, so small waterfall filters or sponge filters are recommended.
Without a filtration system, replace 1/3 of the water weekly to maintain stable water quality.
III. Landscaping and Decorations
Substrate and Hardscape
Choose South Brown Sand or stream sand for the substrate (2-3cm thick) for easy cleaning.
Secure driftwood and stones with aquarium-safe skeleton glue, ensuring no sharp edges that could tear the betta’s fins.
Plants and Vegetation
Opt for low-light-tolerant plants like bamboo grass, Anubias, and Java moss.
Floating plants (e.g., water lettuce or Salvinia) provide shade and reduce the risk of bettas jumping out of the tank.
IV. Precautions
Water Quality Management
Maintain a water temperature of 26-28℃ and a pH level of 6.5-7.0.
Cycle the new tank for at least 2 weeks before adding fish to allow the nitrification system to establish.
Safety Details
Use a breathable lid with a 5cm gap to prevent jumping.
Avoid colored artificial stones or coral, as they may cause chemical contamination.
With proper configuration, a betta tank can both meet ornamental needs and ensure the fish’s health. For more inspiration, refer to landscaping examples in video tutorials.
