Why Choose Outdoor Fish Tanks?
Outdoor tanks add fascination to many yards. Fish keepers get creative when designing outdoor fish tanks! Here are a few good reasons you should choose an outdoor tank. Not only does it provide a decoration factor, but it is also a fun DIY project!
Safety Measures for Outdoor Fish Tanks
Predators and weather elements are a risk to outdoor tanks. We will provide you with the necessary safety measures to reduce potential risk factors your tank may have to endure.
Where to Place an Outdoor Fish Tank
Outdoor fish tanks look best under shady trees, patios, or near outdoor garden tables. If you sit outside often, you will want to place the tank close for easy viewing.
If you regularly have strong winds or scorching hot days, you will need to place the tank under an outdoor sunroof or leafy tree. You can even invest in making a DIY lid to fit the tank.
Outdoor Fish Tank Price Range
Creating an outdoor tank is not the cheapest option in the hobby. You can expect to pay anywhere from $800 to $1,500 if you are creating a large outdoor fish tank that requires a large number of building materials, filtration, and sump systems.
You may have to pay extra for a water fountain if you plan to add one for the beauty and aeration it offers to the outdoor tank while maintaining beauty.
10 Best Outdoor Fish Tank Ideas
1. Washtub Tank
Using a large oval-shaped basin makes an excellent outdoor fish tank! It has a decent depth, and you can easily place large aquatic plants inside the tank using ceramic pots and aquarium soil. You can become creative and even paint the outside to your desired color. Planting brightly colored roses makes it more attractive to any garden. This tank is good for fancy goldfish such as large adult fantails. You can attach a hang-on back filter or use an underwater sump system. Avoid using well water as the iron content will cause the basin to turn a rust color.
2. Old Boat
You can convert a boat into a tranquil little shallow outdoor tank for smaller fish. You will have to treat the wood with an aquarium-based sealant to prevent rotting or leaking. Placing ceramic pots with water lilies and having a side of the boat with duckweeds adds a fascinating aesthetic.
3. Wooden Planter Aquaponic Tank
Using an aquarium place under a wooden planter box looks fantastic against outside walls and under patios. You can use the aquarium water to use on your plants in the box. Starting a vegetable garden above the tank is a potential idea.
4. Pop-up Aquarium
You can purchase a large glass plant vase from a local plant nursery. Adding in plants and dechlorinated water makes it a good outdoor fish tank idea. This allows a clear 365° view of your fish. Avoid placing it in the sun as the size can cause the temperature to fluctuate rapidly.
5. Rock Pound with Fountain
Purchasing a large rock pond with a built-in fountain makes an excellent home for small fish. You can place this in a flower bed to enhance the aesthetic value.
6. General Outdoor Aquarium
You can use a fish tank and place it on a decorative unit outside. Grow vine plants around to bring out the natural appeal in your garden. Floating plants like duckweed will grow well in this type of outdoor tank.
7. Circular Washtub Tank
A circular replica of the oval basin, this design offers a more sophisticated look to planted gardens. This outdoor tank looks good with a large ceramic pot of tall water lilies to add to the height attractiveness. This is ideal for fish such as koi or slim-bodied goldfish.

8. Backyard Grotto
Although building this is more expensive than the other ideas available, the beauty and size are worth it! This tank looks great against walls that are partly shaded. The glass front panel makes viewing your fish easier. This tank works well for goldfish and larger-bodied outdoor fish. Adding pot plants on the stone walls enhances the natural look.

To create this masterpiece, you will need to mold stones and cement around the tanks. To add a supportive base, you can clay wrap bricks and place them on either side. This is overall one of the best outdoor aquariums for minnows and small fancy goldfish. A hang-on-back filter mimics waterfall action.

A large amount of space is suitable for koi or slim-bodied goldfish. Growing tall aquarium plants helps to counteract the overall height appearance and make it look more natural. The glass curved panel allows you to easily view your fish.
