⭐ Why Choose a Glass Aquarium?

🔍 Crystal-clear viewing with low-iron ultra-clear options
💪 Scratch-resistant — far more durable than acrylic
🎨 Clean, modern looks that suit any room
♻️ Long-lasting — quality glass tanks last decades
🧪 Holds water parameters more stably than smaller setups

⚠️ Choosing the Right Size

Bigger is almost always better. Larger tanks dilute waste, hold temperature more steadily, and forgive beginner mistakes that would crash a nano tank. If you're new to the hobby, we recommend starting at 20 gallons or larger for the easiest experience.

🛠 Aquarium Setup Essentials

  • Filtration — Properly sized for your tank's gallons; explore our aquarium filtration collection
  • Heater — One watt per gallon as a starting point; see adjustable aquarium heaters
  • Lighting — Match intensity to your plant selection
  • Substrate — Inert sand/gravel or plant-specific aquasoil
  • Stable, level stand rated for your tank's full water weight

🐟 Stock It Right

Once your tank is cycled, browse our livestock collections to find tankmates that match your aquarium size and style — from tetras and freshwater shrimp to South American cichlids and peaceful community fish. Always research compatibility before adding new fish.

🔍 Frequently Asked Questions

What size aquarium should a beginner start with?
We recommend 20–40 gallons for new aquarists. Larger tanks are more stable, more forgiving, and give your fish more room to thrive.

Glass vs. acrylic — which is better?
Glass is more scratch-resistant, holds clarity longer, and is generally more affordable. Acrylic is lighter but scratches easily. For most home aquariums, glass is the better long-term choice.

Do I need a special stand for my aquarium?
Yes — water weighs about 10 lbs per gallon, so a 40-gallon tank can weigh 400+ lbs. Always use a stand rated for your specific aquarium's full filled weight.

How long does it take to set up a new aquarium?
Plan on 4–6 weeks for a full cycle before adding fish. You can speed this up with seeded media or live bacteria starters.

Can I pick up my aquarium locally?
Yes — local pickup at our Cheyenne, Wyoming shop is available for all aquariums, and our team can help you choose the right size and equipment in person.
