Description

Zebra Danios are highly recommended for beginners, as they are hardy, adaptable to a wide range of temperatures, and thrive even in newly set up aquariums. Even with a filter, aquariums need routine care. Replace about 20% of the water each month to keep the tank clean, reduce waste, and maintain a healthy environment for your fish. Excessive exposure to natural sunlight or artificial lighting can disrupt the balance of the tank, leading to rapid algae growth. 3-4 hours of sunlight per day is sufficient. Attention: Fill filter with water before plugging in. Designed with both functionality and safety, our aquarium cover is perfectly sized to allow easy and convenient feeding while ensuring that your fish stay securely inside. Whether you’re feeding, cleaning, or simply admiring your fish, this cover makes every task easier. Equipped with 5W USB-powered white COB LED to achieve higher light efficiency and lower energy consumption. It brightens your aquatic world for optimal viewing and meets the lighting needs of low-light-demanding plants. Founded in 2017, Wonder Factory is an innovative brand dedicated to smart home appliances. With our All-in-one series available in a range of sizes, customers can effortlessly experience the joy of fishkeeping.

This is my first aquarium, 3 gallon comes with anything I needed. It's easy to set up and its good quality, very solid and clear. I am going to buy some bettas this weekend. This will be a beautiful decoration in my living room.

  • Perfect Start Up Aquarium
Size: 3 Gallon
I never leave reviews but I was so impressed with this kit, I had to say BRAVO! I had a very sick baby Discus fish who had an inflamed bladder. After a couple short epsom salt baths, she settled in to this aquarium and is happily recovering in this tank. The filtration, temperature control and room to swim was perfect. I’m using this as an isolation tank but it’s perfect for a start up set ... show more

  • But your own heater

Tank is good but the heater does not work well at all it broke after 3 weeks of having it and now my betta fish is about to die

  • Happy Goldfishes
Size: 3 Gallon
This small fish tank is good if there will be first time having a fish especially small size. This fish tank has all in one for new starters. It has own light,water filtration without needing any extra filter. The glass is also bright and easy to clean . The set up is also easy which no need to have any experience previously. The material quality is well made and appearance looks pretty well. I use pellets instead of flakes for fish food that also help clean for the tank.At this moment my goldfishes are happy and the size is enough for two. ... show more

  • Don't buy. Something ain't right with the setup.
Size: 3 Gallon
Read the other one star reviews. I don't know what's wrong with the tank, but there's something. Reading the reviews, it seems like the filter is a problem for others. Ours has worked since we plugged it in, as has the heater, but the fish keep dying. We've now lost 8 guppies over two weeks. I used water conditioner and good bacteria to prime the water before putting the fish in, and they still die within 24 hours. This is the second fish tank we've had, and we never had these problems keeping fish alive in the other tank. Going to ask for a refund, but based on other reviews I doubt that will be forthcoming. Seriously, buy someone else's tank and save yourself the hassle. ... show more

  • Good Starter tank
Size: 3 Gallon
It arrived quickly and was dairly easy to set up. Its a nice little take. For a couple of gish. I did take 1 star off because it will hold max 2.75 gallons not 3 and the gravel that it comes with is not ideal

  • Great starter tank
Size: 3 Gallon
I was pleasantly surprised by the quality of this set. The glass tank looks sleek and modern on my desk, and no leaks. The included filter and heater work well, and I like that it comes with gravel, decorative rocks, and basic cleaning tools — it made setup super easy. The light is bright enough to make the tank stand out without overheating the water. Perfect size for a betta or a small aquascape. Definitely recommend if you’re looking for a compact, complete kit. ... show more

  • Beautiful
Size: 3 Gallon
⭐⭐⭐⭐⭐ Amazon Review “Absolutely obsessed with this setup. What started as a simple countertop aquarium turned into the coziest and most peaceful corner in the house.” ✅ Beautiful minimalist aesthetic that looks clean and calming ✅ The soft water flow creates an incredibly relaxing atmosphere ✅ The combination of greenery and water gives a natural spa-like feeling ✅ Black glass tank contrasts perfectly with the bright countertop ✅ Creates a warm, modern, cozy vibe at night ✅ Compact but still feels elegant and intentional ✅ Makes the entire kitchen feel more alive and peaceful ✅ Looks far more expensive and designer-inspired than expected “It feels less like a fish tank and more like a tiny living ecosystem. Every time I walk by it, I stop and stare for a moment.” ✨ ... show more
