Best Aquariums of 2025

"I transitioned from two ten-gallon tanks to this one for my three goldfish, and I'm absolutely thrilled with it. After a few months, there have been no leaks or issues. The rim is still intact without any cracks. I prefer using paper towels for cleaning the glass, as scrapers and sponges didn’t work well on my previous tanks. My only issue is that my fish are growing even bigger. This tank is perfect and the absolute cheapest I could find after extensive searching on Amazon. Highly recommend, 5/5!"

"As someone who has wanted an aquarium since childhood, this tank is taller than I imagined, which might explain why I got it as a used return. Despite that, I couldn't resist the price. My only complaint is the stubborn sticker stuck to the bottom inside; removing it will be a hassle. The height offers more viewing area and a taller water column for activity. Although it’s heavy, it’s not as awkward to handle as I expected. I'm building a multi-tank system, and this tank is a solid foundation. It came with some water treatment packages, which is a helpful touch. This tank is just the beginning of my exciting new hobby!"

"I purchased this tank for my beta fish, and it's fantastic. The size and quality are just right."

"I think this is a great little tank. It's very quiet and looks fantastic. The pump was a bit tricky to set up initially, but it works well now. The LED light is bright and the timer options are a nice touch. I also appreciate the secure lid, which keeps my cats out. I'd highly recommend it!"

"I purchased this tank for my Betta fish, and I love it! It's quiet, the size is perfect, and it looks great. The color-changing light is a fun feature, and the timer is a bonus. It's an incredible deal for what you get, and I'm considering buying another for my son's room because it's so relaxing."

"I recently got this 3-Gallon Aquarium, and while I love the design and size, I've faced some issues. The water filter stopped working just a month in, despite following the cleaning instructions. I reached out for support, but I haven't received any response. It's disappointing to deal with a brand that lacks proper customer service, especially since a functional filter is crucial for a healthy aquarium."

“I love this tank! My plants are thriving with the light system, and the automatic feeder is fantastic. My male Betta seems to enjoy it too. Just a heads-up: beware of cats! The app allows me to manage everything, including a child lock feature. Unfortunately, my cat has cracked the code and is turning everything on and off!”

“So far, I’m pleased with this tank. It shipped in the original box, which had a big hole, but thankfully the tank itself was fine, with just a minor scratch. I really appreciate the back filter compartments and the water temperature readings. However, I believe it’s more of a 3.8-gallon swim space, so I would prefer a lower price.”

“I really enjoy this tank! The integration is impressive, and the WiFi connectivity is a game-changer. I did have some initial trouble connecting to the app, but the customer service on WhatsApp was excellent. They helped me troubleshoot until everything worked flawlessly. This tank is fantastic for anyone who travels often!”

"I am so happy with my tank. This is the biggest aquarium I've ever had, and I am very pleased with everything it came with. It came with the necessities to get started: the tank, heater, and the filter which is powerful and quiet. Couldn't be more pleased. And the fish like it too."

"I loved the tank at first, but then the lights started turning on and off randomly about a month after purchase. Now they have stopped working altogether, and I am unsure what to do for replacements."

"I purchased this Tetra 55 Gallon Aquarium Kit after a year of thinking about it. The tank itself is very well made with heavy tempered glass. The filter also works well, clearing up the water quickly. However, the LED light has issues; it only stays on for about 15 seconds before cycling off. If the lighting worked effectively, I would have rated this a 5-star product."

"I found this aquarium to be the perfect size for my Betta. However, the filter was a bit of a letdown with all the vibrating and noise. I paired it with a quieter option and love that there's room for a heater next to the filter."

"I decided to set up a Betta sorority and grabbed this tank at a great price. The filter pump is absolutely silent, and the design is sleek. It’s a perfect functional piece of art for my space."

"I absolutely love this tank! It’s spacious for my Betta and looks fantastic in my room. The LED light really showcases the tank, but I noticed the filter is a bit loud, so I've been doing frequent water changes instead."

“I absolutely love the beautiful tank! It fit my space perfectly and was easy to set up. The glass top is a great feature for preventing water evaporation and keeping visibility low. Cleaning it is a breeze, and overall, it's the best choice for me.”

“I’m really impressed with the thick glass of this tank. It arrived in perfect condition, and the size is just right for my needs. However, I did notice that the foam pad provided wasn't the black one shown in the photo; it's white instead.”

“While I was excited about the glass lid for my nano orchidarium, I found that it doesn't fit tightly. There's a noticeable gap which might be an issue for keeping my frogs secure. Still, the overall look of the tank is fantastic, and it's just what I needed for the orchidarium.”

"I saved this betta male because he has anxiety and can't be with other fish. Everyone thinks he's just spoiled! The tank is absolutely sleek and easy to set up. I love the step-by-step manual and tips. I would love to get another for my grandkids one day. My only question is about the oil diffuser; it didn't come with any oil, so I'll need to check on that. Get you one; you won't go wrong because I've returned other tanks like this. I'm very happy with my purchase. Thank you!"

"I got this tank for my son's creek fish. I was skeptical about the price, but I went ahead. I love how clear it is, and the settings and abilities it has are awesome. I don't see the point of the diffuser since I won't use it, but others might. The size is just right—not too big or too small."

"I've been using this fish tank for a few months with my son, and overall, it's a decent setup and a great learner tank. The easy-to-read display for pump levels and water temperature is very helpful. The lighting enhances the aquarium beautifully. The multi-filter system works well, but this tank is definitely small—suitable for 1-2 fish max. The lid can be a bit of a hassle, especially with the filtration system. The humidifier feature feels like a gimmick, but it’s there if you want it. If you're looking for a compact aquarium with solid essentials and a nice display, it's worth considering, just don't expect it to house a thriving ecosystem—it's more of a starter tank."

"I decided to ignore the reviews and purchased two of these tanks for my hospital and quarantine needs. Unfortunately, the first one started leaking right away. After 30 years in the hobby, I've never encountered such poor craftsmanship. The filter is practically useless, just a flimsy piece of cotton, and the overall assembly feels like it could collapse at any moment. There are visible defects, from excessive glue to scratches and chips. I wouldn't trust this product with my fish at all!"

"I got this aquarium and was initially impressed with its looks. It came securely packaged, and the lighting has multiple settings. However, I've noticed that the hoses tend to pinch when I lift the lid, and the algae growth is a concern. The filter that comes with it isn't efficient, and I wish I had opted for a larger size or a different brand. Just a heads up, the tank started leaking within six months, which was quite a hassle!"

"This aquarium is just what I needed! It's the perfect size and operates quietly, keeping my fish comfortable. I really appreciate the different lighting options, which create nice moods in the room. Overall, it's easy to clean and assemble, making it a great product for the price!"

"I bought this cute little aquarium for my grandson's Betta fish. The filter's water flow is light, which makes it suitable for the Betta. However, I'm concerned about the lack of replacement filters available."

"I was skeptical about purchasing this micro tank, but for just $28, it fits my shelf perfectly. The USB power is convenient, and I appreciate the quiet operation. However, I wish it were a bit larger for my Betta."

"I love this tank, but I've encountered a problem getting the filter to work properly. Despite this, the overall design and LED lighting are nice."

"When I received the small aquarium, I was initially pleased with its solid glass construction. However, I faced some issues with the rubber connectors shedding material and the clear air tubing being too short. After transferring my Betta fish, he became lethargic and I noticed a strong chemical smell, which was concerning."

"This tank comes with everything needed for my Betta fish to live comfortably. I appreciate the light features and the fact that I don't have to clean it as frequently as a regular tank. My fish seems happy!"

"Setting up this aquarium was relatively easy, and I found the size perfect for my dresser. Although I had some questions about the filter, I figured it out. Overall, it looks great and the water flow is satisfactory."
