Starter Aquarium: Small size of the cube aquarium can be used as a feeding box for tiny aquatic animals such as shrimp and small fish, and can also be used as a viewing box for seaweed and moss balls. The transparent design provides a clear view and complements home decor, and is more pleasing to the eye when stacked, helping to develop children’s observation and curiosity
Block Type Decorative Fish Tank: This is a cute little fish tank with 6 protruding columns at the top, which can be stacked with the same fish tank of different colors to mold multiple fish tanks into different shapes to decorate your table and walls
Easy to Use: The set-up is easy and direct. Hold the transparent inner tank with one hand, hold the outer frame with the other hand and pull in the opposite direction to open the fish tank. The surface of the fish tank is smooth and burr-free, safe for both people and fish

The fish tank currently on display measures 16 cm (6.29 inches) long, 10.5 cm (4.13 inches) wide, and 13.5 cm (5.31 inches) high.

Perfect and cute!
So freaking cute! I bought this for my office to liven the place up. Easy to clean and perfect size for a small table top tank. It came with some rocks and decor for inside as well. Great for the price! And shipped quickly!

Too Small For Permanent Housing But Cute!
For the size that it is. This tank is not to be used for permanent betta tank housing. It is too small as I was told by the Petsmart employee the other day when I bought my female koi betta. They are not to be in less than 1 gallon of water. I have a 3 gallon on the way. This is good for temporary housing until you get a bigger tank. And also good for when you have to clean the main tank. Iâm sure it will be easy to clean too. Seems sturdy, doesnât leak. Great purchase for the money. Thick enough. Was easy to setup.

Decent tank, misleading description
The tank is great for marimo moss balls or toy fish, but it shouldn’t be used for a betta on account of it being way too small. (The proper size is 5 gallons) It also lacks a heater and filter, so keeping fish in it isnt super ideal. It also tends to spill when opened and is a little awkward. It makes a good, cute habitat for marimos and looks so cute. I especially like the coloration

Cute and well made
This is absolutely adorable. I’m not using it for a real fish – mine are Lego, which is a perfect match!

Not a good tank and very small
Not a good tank. Started leaking as soon as we placed water into it. Returned it immediately

Just what I needed for travel!
My guppies have given birth and I’m going to drive two of them to my daughter out of state. I needed something small and that wouldn’t splash water all over the place. This is perfect. My husband punched one of the little tabs out of the top circle so I can put tubing in and add an air stone for the drive. I would never use this permanently for any type of fish. Maybe a snail or two but that’s it. Mine was not scratched at all and appears brand new. I was hesitant about the color but I actually think it gives it a lot of character. My daughter calls it “Hermes orange”, lol.

Tina Roberts –

Très bien pour mini aquarium pour un beta.
Teah –
Tank didnât come with accessories like it says. Quite disappointed
Ashley Ford –
Came as described. Works perfectly as a temporary spot for my female beta. Mine came scratched/cracked but other than that there’s nothing wrong with it and the scratch/crack doesn’t affect anything so far. Will possibly order a second to test how well they stack.
