Choosing the Perfect Aquarium!

From proper aquarium sizing, to the actual type of aquarium you will buy, to the location you plan to display it, let's talk about each of these important factors to getting the results you dream of for your beginner freshwater tank!

Aquarium Size

This plays an important role in your aquarium's success—while smaller tanks around 10-20 gallons work well for beginners, larger tanks of 40+ gallons are actually more forgiving because they provide greater water volume to dilute waste and maintain stable conditions. The bigger your aquarium, the better!

Type of Aquarium

The type of aquarium you choose will determine your entire setup approach, maintenance requirements, and fish selection options. Each path offers unique rewards and challenges that cater to different interests and experience levels.

 

There are various types of aquariums, including freshwater, saltwater, and reef (coral only) tanks. Freshwater aquariums are the easiest for beginners, as they require less maintenance than saltwater options.

Location

This matters significantly for your aquarium's health. You’ll need to choose a spot away from direct sunlight, which can cause unwanted algae growth and temperature fluctuations. You should also avoid areas near heating vents, air conditioners, or high-traffic zones that might stress out your fish. The surface must be perfectly level and sturdy enough to support the substantial weight of a filled tank—remember that water weighs about 8 pounds per gallon.

Beginner Freshwater Aquariums

 

Freshwater aquariums are a good starting point for new aquarists. They offer greater forgiveness for beginner mistakes, lower setup costs, and simpler maintenance routines compared to saltwater tanks. While a bit easier to care for, freshwater tanks still provide endless opportunities for creativity and learning!

Setting Up Your Freshwater Tank

• Substrate: Begin with a quality substrate that serves both functional and aesthetic purposes. Gravel remains the most popular choice for beginners, available in various colors and sizes. Sand creates a more natural appearance and works well with bottom-dwelling fish, though it requires gentler cleaning techniques. Avoid substrates that might alter water chemistry unless you specifically need those effects.
• Filtration System: Your filtration system forms the heart of your aquarium's life support. A good filter should provide mechanical filtration to remove particles, biological filtration to process fish waste, and chemical filtration to remove dissolved impurities. Hang-on-back filters work excellently for most beginner setups, offering easy maintenance and reliable performance. Size your filter to handle at least your tank's full volume, though slightly oversizing provides extra security.
• Temperature: Temperature control becomes essential for tropical freshwater fish. A reliable heater with an adjustable thermostat maintains consistent temperatures between 76-78°F for most tropical species. Always use a separate thermometer to verify your heater's accuracy, as temperature fluctuations can stress fish and compromise their immune systems.

Freshwater Fish for Beginners

 

Start your aquatic journey with hardy, peaceful species that tolerate minor water quality issues while you develop your maintenance skills.

 

When it comes to adding fish, be sure to consider your tank's carrying capacity carefully—the "inch per gallon" rule provides a rough starting point, but fish bioload, swimming habits, and territorial needs are important factors to also consider. You’ll need to research each species' adult size, social requirements, and compatibility before making purchases. Some fish thrive in groups, while others prefer solitary lives or pairs.

 

Here are some of our favorite suggestions for freshwater fish!

 

• Guppies: Offer vibrant colors, active personalities, and overall hardiness, making them perfect first fish.
• Neon Tetras: Create stunning schools with their electric blue and red stripes, while remaining peaceful and undemanding.
• Corydoras Catfish: Serve as excellent cleanup crews, eating leftover food while adding personality to your tank's bottom level.
• Betta Fish: Display spectacular flowing fins and vibrant colors, thriving in smaller, dedicated tanks while being relatively low-maintenance for beginners.
• Platies: Come in a rainbow of colors and patterns, breed easily, and remain peaceful community fish that get along well with most tank mates.
• Cherry Barbs: Add a pop of brilliant red color to your aquarium while maintaining a gentle temperament and schooling beautifully in groups.
• Mollies: Adapt to various water conditions and offer interesting shapes and colors, making them versatile choices for community tanks.

 

When in doubt, be sure to check with experienced freshwater fish professionals. At Sanctuary Aquatics, we can help you choose your ideal freshwater fish to add beauty and life to your freshwater tank!

Freshwater Maintenance Essentials

 

You should establish a regular maintenance routine from day one.

• Water changes: Weekly partial water changes of 20-25% help remove accumulated waste products and replenish essential minerals. Use a gravel vacuum during water changes to remove debris from the substrate while avoiding disturbing beneficial bacteria colonies.
• Feeding: Feed your fish small amounts once or twice daily, providing only what they can consume within 2-3 minutes. Overfeeding ranks among the most common beginner mistakes, leading to poor water quality and fish health problems. High-quality flake food works well for most community fish, supplemented occasionally with frozen or live foods for variety.
• Water parameters: Monitor your water parameters weekly using reliable test kits. Focus on ammonia, nitrite, nitrate, and pH levels initially. Ammonia and nitrite should always read zero in established tanks, while nitrates should remain below 20ppm through regular water changes.

If you’re new to freshwater tanks, we’ve got you! Sanctuary Aquatics has a team with decades of personal and professional experience working with freshwater tanks – from fish, to plants, to proper tank size, to appropriate lighting.

Beginner Saltwater Aquariums

 

If you love the look of a saltwater tank with various fish, coral, anemone, and invertebrate species from the ocean, with a little bit of research, you can get started with setting up your dream tank! While requiring more initial investment and careful attention to detail then a freshwater tank, modern equipment and techniques have made marine aquariums more accessible than ever before.

 

Let’s talk about what you need to know when it comes to saltwater aquariums:

Setting Up Your Saltwater Tank

• Tank Size: Saltwater systems demand higher quality equipment and more precise water parameters than freshwater setups. Start with at least a 40-gallon tank, as larger volumes provide greater stability in the marine environment. The increased water volume helps buffer against rapid changes in salinity, temperature, and water chemistry that can quickly become problematic in smaller systems.
• Substrate: Your substrate choice affects both aesthetics and biological processes. Live sand contains beneficial bacteria that help process waste, while crushed coral provides natural buffering to maintain proper pH levels. Avoid freshwater gravels, as they may contain minerals harmful to marine life or fail to provide necessary chemical buffering.
• Protein Skimmers: These systems are an essential component for saltwater tanks, removing organic compounds before they break down and pollute the water. These devices use fine air bubbles to extract proteins, oils, and other organic materials that standard filters cannot remove effectively. Size your protein skimmer appropriately for your tank volume and expected bioload.
• Water Filtration: Saltwater requires more sophisticated filtration than freshwater systems. Combine mechanical filtration, biological filtration through live rock or ceramic media, and chemical filtration using activated carbon or specialized resins. Live rock serves multiple purposes, providing biological filtration, natural beauty, and hiding places for fish while supporting beneficial bacterial colonies.

All About Coral

Sanctuary Aquatics has an extensive SPS (Small Polyp Stony) and LPS (Large Polyp Stony) coral collection, ranging from easy to care for Zoanthids and Palythoas, to more advanced species like Acropora. If you're just starting out, you'll want to opt for hardy Mushroom, Zoanthids and Palythoas that are more forgiving when you've accidentally made mistakes with some of the tank's parameters. Not only are they easy to keep, they are colorful also and come in a variety of patterns to make your beginner tank look beautiful.

 

As you advance in your saltwater aquarium keeping skills, you can add other species such as the Acanthastrea, Euphyllia, Favia, Blastomussa, and Goniopora. If you want our suggestions, please contact us and we'll help you determine which coral species are best to add to your tank.

Saltwater Fish for Beginners

 

Begin your saltwater aquarium adventure with hardy, peaceful species known for adapting well to aquarium life. Avoid delicate species, aggressive predators, or fish with specialized dietary requirements until you've mastered basic marine aquarium care.

 

Here are a few suggestions for beginner saltwater fish:

• Clownfish: Offer iconic appeal, hardiness, and interesting behaviors, especially when paired with their host anemones. Various species to keep in a beginner aquarium include the Ocellaris Clownfish and Percula Clownfish, which both provide distinctive orange, white, and black coloration, adding color and personality to your aquarium!
• Cardinalfish: Remain peaceful, colorful, and relatively undemanding while adding gentle movement to your tank, with the Pajama Cardinalfish being exceptionally hardy and featuring unique spotted patterns, the Banggai Cardinalfish offering striking black and white stripes with long flowing fins, and the Flame Cardinalfish providing vibrant red coloration.
• Yellow Tangs: Bring bright color and algae-eating benefits, though they require larger tanks and careful attention to diet. The Yellow Tang is the best tang/surgeonfish species for beginners, as other tangs can be more aggressive.
• Gobies: Provide fascinating behaviors and easy care, with popular species including the Firefish (Fire Goby) with their elegant elongated fins, the Yellow Watchman Goby that often pairs symbiotically with pistol shrimp, and the Neon Goby that serves as a natural cleaner fish while staying small and peaceful.
• Wrasses: Add active personalities and pest control benefits to your tank, with beginner-friendly options like the Sixline Wrasse that helps eliminate unwanted hitchhikers, the Fairy Wrasse species (such as the Solar Fairy Wrasse) that bring brilliant colors and peaceful temperaments, and the Halichoeres Wrasses like the Yellow Coris that remain smaller and less aggressive than larger wrasse species.

Research each species' specific needs, including tank size requirements, social behaviors, and dietary preferences. Many marine fish grow larger than their freshwater counterparts and require more swimming space.

 

Consider the order of introduction carefully, as territorial disputes can arise when new fish enter established territories. Add less aggressive species first, allowing them to establish territories before introducing more assertive tank mates.

Saltwater Maintenance Essentials

Saltwater maintenance requires greater precision and consistency than freshwater systems, to ensure that your fish, coral, and invertebrate species thrive in their environment. Here are some important steps to take to ensure success:

• Water Changes: Weekly water changes of 10-15% help maintain water quality and replenish trace elements consumed by marine life. Always mix new saltwater in advance, allowing it to reach proper temperature and salinity before use.
• Checking Salinity: Salinity monitoring becomes crucial, as evaporation concentrates salt levels while only pure water evaporates. Use a reliable refractometer or hydrometer to maintain salinity between 1.020-1.025 specific gravity. Top off evaporated water with fresh dechlorinated water, never saltwater, to maintain proper salinity levels.
• Water Parameters: Test water parameters more frequently than in freshwater systems, monitoring ammonia, nitrite, nitrate, pH, alkalinity, calcium, and phosphate levels. Marine organisms often show greater sensitivity to water quality fluctuations, making consistent monitoring essential for long-term success.
• Feeding: Research what and how to feed your marine fish and corals high-quality foods. Many marine fish require varied diets including algae, meaty foods, and specialized supplements.
