When planning your next aquarium setup, understanding the dimensions of a 30 gallon aquarium is essential. Whether you’re housing tropical fish, creating a planted tank, or designing a centerpiece for your home or office, size matters—not just in volume, but in length, width, and height.
✅ Standard Dimensions of a 30 Gallon Aquarium
A typical 30 gallon fish tank generally comes in two common shapes:
| Type | Length | Width | Height |
|---|---|---|---|
| 30 Gallon Standard | 36 inches | 12 inches | 16 inches |
| 30 Gallon Breeder | 36 inches | 18 inches | 12 inches |
🔍 Tip: Breeder tanks are shallower and wider, making them ideal for aquascaping or breeding setups.
🪟 Material Matters: Glass vs. Acrylic
If you’re aiming for durability and clarity, ultra-clear low-iron glass is an excellent choice. Compared to standard glass or acrylic, it offers better visibility and scratch resistance—perfect for showcasing vibrant aquatic life.
One such example is the YEE Ultra Clear Desktop Glass Fish Tank, which features premium glass clarity and a minimalist design. While designed for desktops and smaller setups, YEE also offers custom-sized tanks, including 30-gallon options, to suit your specific space and style needs.
🐟 What Can You Keep in a 30 Gallon Aquarium?
A 30 gallon tank gives you enough space to keep a variety of freshwater or saltwater species, such as:
- Guppies, mollies, and platies
- Dwarf gouramis or angelfish
- A small group of tetras or rasboras
- Shrimp, snails, and peaceful bottom dwellers
- Aquascaped planted setups or nano reefs (with the right equipment)
🧠 Remember: Always consider filtration, bioload, and swimming space when planning your stocking.
💡 Choosing the Right 30 Gallon Aquarium for You
When shopping for a 30-gallon tank, consider the following:
- Dimensions & Placement: Will it fit your stand or countertop?
- Material: Opt for low-iron glass for crystal-clear viewing.
