Insufficient power of the adapter may cause the light or the pump not working. If the pump stops working or the water flow decreases, it is time to remove the pump, clean it thoroughly, and then properly reinstall the impeller and shaft assembly to restore normal operation. And the pump need to be FULLY SUBMERGED UNDER WATER to work.

- SHOWCASE THOSE BEAUTIFUL COLORS: While keeping your Bettas safely separated, the double-sided divider is both opaque and see-though. If you wish to keep your fish from seeing one another, keep both sides of the wall down.

The Ultimate Buying Guide for Your Betta Fish Tank
Bringing home a betta fish, or Siamese fighting fish, is exciting! These colorful, elegant fish deserve a happy home. Choosing the right tank is crucial for their health and happiness. This guide helps you select the perfect setup.
Key Features to Look For
When shopping, several features make a big difference in tank quality and your betta’s life.
1. Size Matters Most
- Minimum Size: Never choose anything smaller than a 5-gallon tank. Smaller tanks (like bowls) cause stress and quickly pollute the water.
- Ideal Size: 10 gallons or more gives your betta plenty of room to swim and explore.
2. Filtration System
Betta fish produce waste. A good filter keeps the water clean. Look for filters that are gentle.
- Sponge Filters: These are often the best choice. They clean the water without creating strong currents. Bettas dislike strong water flow.
- Adjustable Flow Filters: If you choose a hang-on-back filter, ensure it has a way to lower the water flow rate.
3. Heating Element
Bettas are tropical fish. They need warm, stable water temperatures.
- Built-in Heater: Many modern kits include an adjustable heater. This is a huge plus.
- Temperature Range: Ensure the heater keeps the water between 76°F and 80°F (24°C to 27°C).
4. Lid or Cover
Bettas are jumpers! A secure lid prevents accidental escapes. The lid should also allow airflow for gas exchange.
Important Materials in Tank Construction
The materials used determine the tank’s safety and longevity.
Glass vs. Acrylic
- Glass Tanks: These are durable and scratch-resistant. They often provide clearer viewing. They are heavier than acrylic.
- Acrylic Tanks: These are lighter and shatterproof. However, acrylic scratches easily during cleaning.
Substrate and Decorations
Choose safe materials for the bottom (substrate) and decorations.
- Substrate: Gravel or sand works well. Avoid sharp, rough materials that could damage your betta’s delicate fins.
- Decorations: Opt for smooth rocks, silk plants, or specialized betta-safe plastic plants. Real driftwood is excellent but must be properly prepared before use.
Factors That Improve or Reduce Quality
Quality isn’t just about the brand; it’s about the design features.
Quality Boosters
- Low Water Flow Design: Tanks specifically designed for bettas often incorporate features that baffle the filter output, ensuring calm water.
- Complete Kits: Kits that include a heater, light, and filter save you money and ensure the components work well together.
- Easy Access: A tank with a wide top opening makes feeding and maintenance much easier.
Quality Reducers (Avoid These!)
- Tiny Bowls or “Betta Buddies”: These are often too small (under 3 gallons) and lack space for essential equipment like heaters. They severely limit your betta’s lifespan.
- Sharp Plastic Plants: Hard, cheap plastic plants shred the long, flowing fins of male bettas, leading to infection.
- No Heater Included: If a kit lacks a heater, you must buy one separately. A cold betta becomes sluggish and sick quickly.
User Experience and Use Cases
How you plan to use the tank affects your choice.
Beginner Setup
If you are new to fish keeping, choose a 5-gallon or 10-gallon “all-in-one” kit. These kits simplify the setup process. You will still need to learn about water changes and testing, but the basic hardware is provided.
Aesthetic Display
If the tank is for a desk or living room display, look for tanks with modern, sleek designs and good integrated lighting. Ensure the light spectrum promotes plant growth if you plan to add live plants.
Office or Dorm Room Use
For smaller spaces, a 5-gallon tank is manageable. Prioritize a quiet filter system so it does not disturb work or sleep. Always confirm that the facility rules allow fish tanks.
10 Frequently Asked Questions (FAQ) About Betta Fish Tanks
Q: What is the absolute minimum size tank for one betta?
A: The absolute minimum size recommended by most experts is 5 gallons. Anything smaller causes significant long-term stress.
Q: Do I need a filter if I use a 10-gallon tank?
A: Yes, filtration is essential. Waste builds up quickly. A gentle sponge filter is highly recommended for bettas.
Q: How often should I clean the tank?
A: You should perform a partial water change (about 25%) once a week. A full clean-out is rarely necessary if you maintain weekly changes.
Q: Can I keep two male bettas together?
A: No. Male bettas are highly aggressive towards each other and will fight until one, or both, are severely injured or killed. Keep them separate.
Q: What kind of light do I need?
A: Bettas need a simple LED light for about 6 to 8 hours a day. If you have live plants, you need a light specifically rated for plant growth.
Q: Are colored gravels safe for my betta?
A: Most dyed gravels are safe, but always rinse them thoroughly before use. Avoid any gravel that looks dusty or has sharp edges.
Q: What is “cycling” a tank?
A: Cycling is the process of building up beneficial bacteria in your filter and substrate before adding your fish. These bacteria break down toxic fish waste.
Q: Can I put snails or shrimp in with my betta?
A: Sometimes. Some bettas ignore snails and small shrimp, but others view them as food. Introduce tank mates cautiously after your betta has settled in.
Q: My tank kit came with a plastic plant. Should I use it?
A: If the plastic plant has sharp tips, replace it immediately with silk plants or live/artificial soft plants to protect your betta’s fins.
Q: Why is the water temperature so important?
A: Bettas come from warm, shallow waters in Thailand. Cold water lowers their immune system, making them susceptible to diseases like Ich.
