Starting your first aquarium is an exciting step into the world of fish-keeping! Whether you’re drawn to the vibrant colours of freshwater tropical fish or the fascinating variety of marine species, setting up a home aquarium can be both rewarding and relaxing. At Aqua Group, we make it easy to get started with healthy, hand-selected fish and all the essentials you need to succeed.
Freshwater vs. Marine – Which is Right for You?
Before diving in, you’ll want to decide whether you’d prefer a freshwater or marine (saltwater) setup.
-
Freshwater Aquariums:
Perfect for beginners, with a wide range of hardy, colourful fish like tetras, guppies, and angelfish. They’re easier to maintain and usually more budget-friendly.
-
Marine Aquariums:
Best for those looking for something truly spectacular. Saltwater tanks can host clownfish, tangs, and even corals, but they do require more equipment and knowledge to maintain stable water conditions.
Both options can be rewarding, you just need to choose what fits your lifestyle and budget.
Step 1: Choosing the Right Tank
The bigger the tank, the more stable it is. A 60–100 litre tank is an ideal size for beginners, giving you enough water volume to make maintenance easier. Consider where your tank will sit at home—avoid direct sunlight, which can cause algae growth, and make sure the stand can support the weight once it’s filled with water, rocks, and substrate.
Step 2: Essential Equipment
A successful aquarium needs more than just water and fish. At Aqua Group, we recommend the following basics:
- Filter – Keeps the water clean and clear.
- Heater – Essential for tropical species.
- Lighting – Not only for your fish but also if you plan to keep plants or corals.
- Water test kits – Help monitor pH, ammonia, nitrite, and nitrate levels.
Step 3: Setting Up Your Aquarium
- Rinse your substrate (gravel, sand, or marine-specific substrate) to remove dust.
- Add decorations and plants/rockwork – These create hiding spots and make your tank look natural.
- Fill with water – Use a water conditioner for freshwater tanks or marine salt mix for saltwater.
- Start your filter and heater – Let your aquarium run for a few days before adding fish.
Step 4: Cycling Your Tank
This is one of the most important steps for beginners! Cycling establishes beneficial bacteria that break down harmful fish waste. It usually takes 3–4 weeks, and during this time you should test the water regularly. Adding fish too early can cause stress or loss, so patience is key.
Step 5: Choosing Your First Fish
When your water tests show stable conditions, it’s time for the fun part—adding fish! At Aqua Group, we stock a wide range of freshwater favourites (like guppies, mollies, and barbs) as well as marine showstoppers (like clownfish and wrasse). Start with a small group and gradually build your community to avoid overloading your filter.
Step 6: Ongoing Care
Your fish will thrive if you:
- Perform weekly water changes (10–20%).
- Test water parameters regularly.
- Feed a balanced diet (and avoid overfeeding).
- Keep an eye out for signs of stress or illness.
Common Beginner Mistakes to Avoid
- Adding too many fish too soon.
- Skipping the cycling process.
- Overfeeding (which can cause cloudy water).
- Not researching species compatibility.
