Cheap and easy tank for beginners
So I've had this aquarium for give or take a month and I love it. the lights give the aquarium and good look and nice touch. the filter that it comes with is ok but if you have another one laying around that's better I suggest using that one because the filter that is included in the box some times makes weird noises and or stops working for a bit, so i have to unplug it for five minutes give or take to make the filter come back on. overall without a doubt, this is a perfect size and low maintains for beginners.

GREAT OPTION TO CONSIDER!
VERY NICE Beginner's Aquarium! Large enough to enjoy creating a nice bioscape or artificial landscape for your new community tank! As goldfish must be in a separate tank than my very large Angelfish community tank, I am choosing to use this tank as a separate aquarium for my 2 small, young gold & black calico fantails. Adding 2 Nerite Snails complete the natural setup views. The built in light works very nicely with the flip open tank lid making access to the ENTIRE aquarium for feeding, cleaning and using tools to reposition tank items easy and carefree! The filter is quiet and hoping replacement filters are easy to order and reasonably priced on Amazon. The only downside, if you could call it that, is that you'll need pliers to break off the tabs allowing extra openings to the lid for a submersible heater, LED Bubbler lights, etc. I highly recommend this sturdy, plastic tank for both beginners and those looking for extra tank setups at a convenient price.

Good tank overall, but flimsy and lid isn’t secure
For $36, this tank is very nice. It has a nice aesthetic, and my goldfish loves all the extra space in this tank compared to his 3 gallon tank. Everything came working, the tank did not have any cracks, but it was scuffed along the bottom. This however is not a problem as it’s not viewable. I also love how the lights are built into the lid of the tank, its very easy to use, and i love how it lights up the tank. My main concern with the tank, is that although it said it is acrylic, it’s not sturdy like my 3 gallon acrylic tank. The plastic on the side is bendable, so that is something to be aware of. I would not recommend moving this tank if it’s full as it may break. My other main concern is that with the filter in, the lid of the tank does not fit securely. I’m not sure if this is just a problem with my particular tank, but i plan to put something on top of the lid to weigh it down so my nosy cats don’t try to open the lid to get at blub blub (my fish). Tl;dr Overall, a nice tank. It fits my needs, it was a cheap upgrade to get my fish more space, which he is loving. I’m not planning on moving the tank, and will plan to just do water changes to keep the tank clean, and plan to just add something to the top of the lid to make sure my cats don’t get into the tank. I also plan on cutting out the heater spot designated on the lid, to add an aerator, as there isn’t another spot in the tank that will fit one.

Great Aquarium!
First of all, this is a really cool product! It came complete with a filter and we love the color changing bulbs. After we installed this in our family room, we had so many people comment on it and inquire where we purchased it. It actually made a few people want to get some fish, just so they could have the aquarium. The filter began to malfunction after about 5 months, so I was trying to purchase a replacement and wrote the company for the order information. Before I knew it, they had already sent a replacement for free! I thought I was still waiting to hear back from the about for the product information. So, I highly recommend this product. Great aquarium and great company!

Filter system does on last
This aquarium is as pictured however after only a little over 3 months of use the filter is failing and making a high pitch screeching sound. Would not recommend. The filter is cheap and not durable for the aquarium system.

Highly recommend
Beautiful and an amazing value! I keep bettas as a hobby (and pets) but the inner child in me has always wanted glofish! So the number of color options and easy viewing angles w/this tank was ideal for me. I was concerned w/some of the reviews stating that there was no cover over the lighting causing rust and shortages. As the lightning was going to be tge main reason for me to purchase I was pretty nervous. However my hood has a thick plastic shield secured over tge light strip (perhaps they've made upgrades?). Its great that it comes with a filter as an almost all-in-one tank, especially if you're new to the game. However i wasn't a fan. It's an unusual and awkward shape and just doesn't seem like the right fit for this size tank. Over the yrs I've compiled extra everything, including several filters, so i used one of my own that blends almost completely into the background. If you don't have extras tho i imagine the one included would work just fine. Less money to pump into equipment. Like other reviewers, the acrylic did have some scuffs, but i expected that having used acrylic for some time now. Some scratches wiped off but ultimately when its filled with water the scuffs are virtually non existent. The hood is great. It has a nice weight to it which is important for me since i have a cat, and i like that it doesn't "attach" to the tank with clips etc. But rather has pegs to rest in specific grooves of the tank, making it easy to open and close for water changes and feeding, but still one less thing to break.
