What Is the Downtown Aquarium?

Located in the heart of Houston, the Downtown Aquarium is a 500,000-gallon aquatic wonderland spread across six acres. It combines a public aquarium, restaurant, rides, and conservation efforts into one unforgettable destination.

Its habitat-themed exhibits take visitors through the rainforests of South America, the marshes of Louisiana, and even shipwrecked ruins filled with mysterious sea life.

Major exhibits include:

• Shipwreck

• Rainforest

• Sunken Temple

• Gulf of Mexico

• White Tiger Exhibit

• Stingray Reef

But for freshwater aquarium lovers, the Rainforest and Sunken Temple exhibits stand out — featuring massive Amazonian fish and colorful oddball species rarely seen in private aquariums.

Step 3: Match the Environment

To give your fish the best possible quality of life, replicate their natural habitat. This is exactly what the Downtown Aquarium does — and you should too.

Key tips:

• Filtration: Use canisters or sumps for large bioloads.

• Heating: Most tropical species thrive at 78–82°F.

• Lighting: Go for natural spectrum LEDs or low-light for nocturnal fish.

• Décor: Use driftwood, river stones, sand substrate, and background foliage.

• Tank Size: Bigger is better. Many monster fish grow over 2 feet long!
