If you want to enjoy an aquarium without the hassle of constant upkeep, this guide will help you set up and maintain a low-maintenance aquarium that still looks beautiful.

1. Choose the Right Tank Size

  • Smaller Tanks: While they may seem easier to manage, small tanks tend to become imbalanced quickly, making it harder to maintain water quality.
  • Larger Tanks: A 100-litre tank or larger offers better stability, meaning the water parameters fluctuate less dramatically. Larger tanks also give fish more room to thrive.
  • Tip: A tank of around 100-200 litres is ideal for beginners looking for an easier-to-manage setup.

2. Select Hardy, Easy-to-Care-For Fish

  • Fish: Opt for species like goldfish, bettas, guppies, or tetras, which are known for being resilient and adaptable.
  • Stocking Levels: Be sure to follow the “one inch of fish per litre” rule, but be cautious of overcrowding, which can lead to problems like poor water quality.

3. Opt for Low-Maintenance Plants

  • Plants: Choose hard-to-kill plants like Java Moss, Anubias, or Cryptocoryne. These plants require minimal light and can survive without constant attention.
  • Tip: Use plants with slow growth to reduce the frequency of trimming.

4. Install a Reliable Filtration System

  • Filtration: Choose a filtration system with adjustable flow rates so you can customise it to the needs of your fish and plants.
  • Maintenance: Perform regular water changes, remove debris manually, and clean the filter every 4-6 weeks to keep the tank low-maintenance.

5. Control Algae Growth

  • Lighting: Set your lighting to be on for 6-8 hours a day to prevent excessive algae growth.
  • Fish and Invertebrates: Consider adding algae-eating species like snails or shrimp to help manage algae naturally.

Benefits of Low-Maintenance Aquariums

  • Less Time-Consuming: With the right setup, you’ll spend less time on cleaning and more time enjoying your aquarium.
  • Sustainable: These aquariums offer a more balanced ecosystem, which requires fewer interventions.

Aquarium Setup for Betta Fish

Betta fish are a popular choice due to their vibrant colours and manageable size. However, they require a specific setup to thrive in an aquarium.


1. Tank Size

  • Minimum Size: Betta fish need at least a 40-litre tank to swim comfortably. Avoid small bowls, as they restrict movement and cause stress.
  • Tip: The larger the tank, the easier it is to maintain water quality.

2. Water Parameters

  • Temperature: Betta fish thrive in warmer water, ideally between 24°C and 28°C. Use a heater to maintain a consistent temperature.
  • pH: Maintain a neutral pH of around 7.0, though they can tolerate slightly acidic or alkaline water.
  • Filtration: Choose a gentle filter, as bettas don’t like strong currents. Sponge filters are a good option for maintaining water quality without causing distress.

3. Tankmates

  • Solo Housing: Bettas are territorial, especially males, and should be housed alone or with peaceful, non-aggressive species.
  • Compatible Tankmates: Consider adding peaceful species like Corydoras catfish or snails. Avoid keeping them with fin-nipping fish like tetras or other bettas.

4. Aquascaping

  • Plants: Betta fish enjoy having plenty of plants for cover. Floating plants like duckweed or water lettuce offer resting spots, while tall plants like Amazon Sword provide a natural environment.
  • Decor: Avoid sharp objects in the tank, as they can tear the betta’s delicate fins. Use soft, smooth decorations instead.

5. Feeding

  • Diet: Betta fish are carnivores and should be fed high-quality betta pellets, supplemented with live or frozen foods like brine shrimp or bloodworms.
  • Tip: Feed your betta in small amounts twice a day to avoid overfeeding.

By following these guidelines, you can create a comfortable, thriving environment for your Betta fish, allowing them to show off their full range of vibrant colours and behaviours.
