I wish it was bit longer instead of taller. Most of your gallons are in height but the tank itself is beautiful and my sharks love it. Easy to clean and the heater that comes with it works great to keep the water warm. I have no leaks or cracks and the filter that comes with it works good. It is a bit louder than other ones but it puts in work. And had a great waterfall sound. It is decently heavy so be prepared to lift with your knees. All in all it’s a great tank and great size for little tetras and angelfish. ... show more

    • The tank itself is wonderful, the stuff it came with, not so much.
Color: Tetra Size: 20 gallon
First, set up was incredibly easy. I had new decor I bought anticipating the decor pictured. It came with some incredibly bright pieces. The lighting is good. The filter started off loud, got quiet, and now I think I need to purchase a different one. It is incredibly loud and obnoxious. Now for the really bad, the heater that was included doesn't work as described. After it said it came to temp, I transferred my fish. My three school fish died overnight. I thought I had done something wrong with the transfer, like not put enough of the old tank water in or something like that. My angelfishes seemed to be doing better. The next day, one of my angelfish was really struggling. I placed a digital heater in there and the temp read 68. The fish died. I currently have one fish that survived. I am disappointed. I need to purchase a different filter for the noise. I keep this in my classroom, so the noise is distracting the kids from focusing. ... show more

    • Broken filter, bad fake plants, 5 stars!!!
Color: Tetra Size: 20 gallon
Review Image by Jon Day Jon Day
So let me start with the bad. The thermometer is a plastic stip that doesn't work. The horrible plastic plants will hurt most fish. The filter was broken and sounded like a bunch of rocks were grinding inside it. And the light is a super basic on off. Now why you should buy this over all the other tanks. That's the tank and the price. The tank is a perfectly functional 20 gal fish tank. It has a nice lid. And I was surprised I liked the heater. All this for less than what a 20 gal fish tank without a lid would normally cost. Seriously just replace the stuff you don't like. The tank alone is worth the price. My tank has been set up for a month now. Photo attached. ... show more

I reached out to company by phone and their contact sheet. No response. Clamps broken on light. Light is wrong light for the tank. Doesn’t fit under the lid at all and can’t go on back of tank due to filter and can’t go on side of tank due to its to long for the side. It’s fully not what’s advertised at all on the lights or how to install at all. The material is flimsy for lid and lid and clamps to lid are broken on one side and lid is cracked. Was a birthday gift I got bc my birthday is this week. Can’t send it back bc I don’t have the box. Figured it would all be new and nothing broken. I even went out and bought new items and rocks and new filters and lucky bamboo to add next week. Just tried tonight to finally take it off the counter and look at it and try to see if I could get it ready to cycle. Noticed the crack in the lid first. Thought okay it’s fine. Won’t be a big deal but nope then notice the lights are not even the right lights for the tank at all. Like no comparison to what’s suppose to come with it. So now I have cracked lid and no lights at all. Not to mention two clamps were broken as well. One for lid and one for the light that doesn’t even fit this tank. So I stopped their and didn’t even bother to look at the rest. Just done and out 160 plus dollars for a twenty gallon tank that has no lid and no lights. I could have bought a 20 gallon at pet store for 20$ on sale for what I got for this. If I could give zero stars I would for lack of communication and failure to help ... show more

    • Great tank, hard to find replacement lights
Color: Tetra Size: 20 gallon
This is a fantastic tank. I purchased it in September 2022, and set it up in October. I haven't had any issues with it, and the same fish I bought then are still happy and healthy! As of today though (July 30th 2025) the light strip has started to flicker and shut off on its own. I have been looking for replacement lights, but the lights in this hood are very unique and I cannot seem to locate a replacement. After searching Amazon, customer reviews, the Web at large and the company site, I still haven't located this particular light strip. I did call and left a message with customer service as it's after hours over East where their headquarters are. I hope to hear back soon with some options, but am wondering if anyone has had to replace the light and may have other resources? ... show more
