Think about tank size, shape, material, and where you will place it in your home or office.
Size And Shape Options

- Cube shape: fits small areas
Material Choices
Fish tanks usually come in glass or acrylic. Each material has benefits and drawbacks to consider.

- Glass: sturdy, clear, heavy, scratch-resistant
- Acrylic: light, clear, easier to shape, scratches easily
Placement Considerations
Place your tank where it gets stable temperature and good viewing. Avoid direct sunlight to stop algae growth.
Make sure the surface can hold the tank’s weight. Keep it away from busy areas to reduce stress on fish.
