Are you a passionate aquarist looking to create a stunning aquatic oasis in your home? Look no further! In this article, we will guide you through the process of finding the perfect 35 gallon aquarium to bring your underwater world to life. From choosing the right tank size to selecting suitable equipment and decorations, we’ve got you covered. Let’s dive in!

Why a 35 Gallon Aquarium?

Before we delve into the details, you might wonder why a 35 gallon aquarium is the ideal choice for your aquatic oasis. Well, this size offers a great balance between spaciousness and manageability. It provides ample room for a variety of fish species and aquatic plants, while still being compact enough to fit comfortably in most homes. A 35 gallon tank is also easier to maintain compared to larger aquariums, making it perfect for both beginners and experienced hobbyists.

Factors to Consider

1. Tank Dimensions

When selecting a 35 gallon aquarium, pay attention to its dimensions. A tank with appropriate length, width, and height will create a visually appealing and functional environment for your aquatic friends. Consider the available space in your home and choose a tank that fits seamlessly into your desired location.

2. Glass or Acrylic?

The material of your aquarium is an essential consideration. Glass tanks are sturdy, scratch-resistant, and provide excellent clarity. On the other hand, acrylic tanks are lighter, more impact-resistant, and offer a wider range of shapes. Decide which attributes are most important to you before making a choice.

3. Filtration System

Maintaining clean and healthy water is crucial for the well-being of your aquatic ecosystem. Look for a 35 gallon aquarium that comes with an efficient filtration system. A combination of mechanical, chemical, and biological filtration will ensure optimal water quality and reduce the frequency of water changes.

4. Lighting

Proper lighting is vital for the growth of aquatic plants and the overall aesthetics of your aquarium. Choose a tank that includes high-quality LED lighting with adjustable brightness. This will allow you to create the perfect ambiance and provide the necessary light spectrum for your underwater flora and fauna.

5. Heating and Temperature Control

Different fish species have specific temperature requirements. To maintain a stable and comfortable environment for your aquatic pets, opt for a 35 gallon aquarium that includes a reliable heater and a thermometer. This will enable you to regulate the water temperature with ease.

Setting Up Your Aquarium

Now that we’ve covered the key factors to consider, let’s move on to setting up your aquatic oasis.

1. Cleaning and Conditioning

Before introducing any fish or plants, thoroughly clean the aquarium and its accessories. Use warm water and a non-toxic aquarium cleaner to remove any dirt or residue. Once clean, condition the water with a suitable water conditioner to neutralize harmful chemicals such as chlorine or chloramine.

2. Substrate Selection

Choosing the right substrate is important for both the aesthetic appeal and the well-being of your aquarium inhabitants. Gravel, sand, or a combination of both can be used. Research the specific needs of your fish and plants to determine the ideal substrate type and depth.

3. Aquascape Design

Let your creativity flow as you design your aquascape! Create depth and visual interest by incorporating rocks, driftwood, and live plants. Consider using different textures and colors to mimic natural underwater environments. Ensure that you leave enough open swimming space for your fish to thrive.

4. Cycling the Aquarium

Cycling your aquarium is a crucial step to establish a healthy biological filtration system. Allow the tank to run for several weeks before introducing any fish. This will allow beneficial bacteria to grow and convert harmful ammonia into less toxic substances, ensuring a safe environment for your aquatic creatures.

Maintaining Your Aquatic Oasis

1. Regular Water Testing

To ensure the well-being of your aquatic pets, it is essential to regularly test the water parameters. Invest in a reliable water testing kit to monitor ammonia, nitrite, nitrate, pH levels, and other important factors. This will help you identify any issues and take corrective actions promptly.

2. Regular Water Changes

Regular water changes are necessary to remove accumulated toxins and maintain optimal water quality. Aim to replace 20% of the water every two weeks or as needed. Use a siphon to remove debris from the substrate during water changes, keeping the aquarium clean and healthy.

3. Feeding and Nutrition

Providing a balanced diet is crucial for the health and vitality of your fish. Research the dietary requirements of your specific species and offer a variety of high-quality foods. Overfeeding can lead to water pollution and health problems, so feed your fish in moderation.

4. Algae Control

Algae growth is a common concern in aquariums. To keep it under control, maintain a consistent lighting schedule and avoid excessive exposure to sunlight. Introduce algae-eating fish or snails that can help control algae growth naturally. Regularly clean the glass and decorations to prevent algae buildup.


Creating a stunning aquatic oasis in your home starts with choosing the perfect 35 gallon aquarium. Consider factors such as tank dimensions, material, filtration system, lighting, and temperature control. Once your aquarium is set up, focus on maintenance tasks like regular water testing, water changes, feeding, and algae control. With proper care and attention, your aquatic oasis will flourish, providing endless enjoyment for both you and your aquatic friends.


1. Can I keep saltwater fish in a 35 gallon aquarium?

While it is possible to keep some smaller saltwater fish in a 35 gallon aquarium, a larger tank is generally recommended for saltwater setups. Saltwater aquariums require more complex filtration systems and additional equipment to maintain stable water conditions.

2. How many fish can I keep in a 35 gallon aquarium?

The number of fish you can keep in a 35 gallon aquarium depends on various factors, such as the size and species of the fish, their territorial behavior, and their compatibility. As a general guideline, aim for one inch of fish per gallon of water to ensure adequate space and minimize stress.

3. Can I use live plants in a 35 gallon aquarium?

Absolutely! Live plants can enhance the beauty of your aquarium and provide numerous benefits, such as oxygenation, nutrient uptake, and natural filtration. Choose plants that are suitable for your lighting and water conditions, and enjoy the lush greenery they bring to your aquatic oasis.

4. How often should I clean my aquarium?

Regular maintenance is essential for the health of your aquarium. Clean the glass, decorations, and equipment as needed to remove algae or debris. Perform partial water changes every two weeks or when water parameters deviate from the desired levels. Avoid cleaning the entire tank at once to preserve beneficial bacteria.

5. Can I keep different species of fish together in a 35 gallon aquarium?

Yes, you can keep multiple species of fish together in a 35 gallon aquarium, but it is crucial to consider their compatibility. Research the temperament, size, and specific requirements of each species to ensure they can coexist peacefully. Avoid mixing aggressive and territorial species to prevent conflicts.
