2.1 Choosing the Right Location

“Location, location, location!” It’s not just a real estate thing—it matters a lot for aquariums too. Where you place your tank affects not only how it looks but also how well your fish will thrive.

🚫 Places to Avoid:

  • Near windows → Sunlight = algae + temperature spikes
  • Under aircon vents → Constant cold drafts = stressed fish
  • Next to doors/TVs → Loud noises = jumpy fish
  • Kitchens, balconies, bathrooms → Just…no 😅

✅ Best Practice:

Pick a quiet, cozy spot where you enjoy relaxing. Your tank should feel like a piece of living art, not a stressor for you or your fish.

Pro Tip: Use a spirit level to check if the surface is flat before placing your tank. For larger tanks (1m and above), double-check your floor’s load capacity—especially in apartments!

Types of Aquariums: Know Your Tank

Now, let’s talk tanks. You might think, “Aren’t all aquariums just glass boxes?” But there’s more than meets the eye!

Materials: Acrylic vs Glass

Glass Types: Not All Glass Is Equal!

Let’s geek out a little (in a fun way). Here’s a quick breakdown of the most common types of aquarium glass:

🔍 Pro Tip: Clear glass makes a world of difference—especially if you’re keeping colorful fish like neon tetras, discus, or bettas, and vibrant plants like Rotala or Ludwigia. Opti-white or crystal glass removes the green tint you’d get from regular glass, so every shade of red, blue, orange, and green pops just the way nature intended. It’s like switching from SD to full HD.

🔍 Pro Tip: While ultra-clear glass like opti-white and crystal glass offers stunning clarity that makes fish and plant colors pop, don’t worry if you’re using a float glass tank—most of the tanks we use in our stores are float glass too! With proper water quality, good lighting, and a well-matched background or base wallpaper, your tank can still look absolutely vibrant.

Many hobbyists choose to save on glass type and instead go for higher glass thickness and Euro bracing—a smart move that enhances both the safety and durability of the tank over time, especially for larger builds.

🔧 Need something more tailored? Whether you’re looking to customise your tank size, add a bracing system, or even build in a full filtration setup, just speak to any of our store team members. We offer custom tank builds and installation packages to help bring your dream aquarium to life—from glass to greenery.

💡 Which One Should You Get?

  • Going all-in for aquascapes or display tanks?
    → Go for Opti-White or Crystal Glass
  • On a budget or using a black background?
    Float Glass is perfectly fine!

Also, keep an eye on the silicone work:

  • Black Silicone pairs well with black backgrounds.
  • Transparent Silicone gives a cleaner, minimalist vibe.

Either way, fish often feel safer with a dark background—so don’t be surprised if they show off their best colors!

🧠 Recap: Let’s Wrap This Up!

Here’s what you’ve learned in this chapter:

Location matters—no direct sun, drafts, or noise.
Check floor level and weight capacity—especially for large tanks.
Acrylicclearer, lighter, pricier, scratches easily.
Glassheavier, affordable, great for most setups.
Float vs Opti-white vs Crystal—choose based on clarity needs and budget.
Backgrounds & silicone types affect both looks and fish comfort.
