    • 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

    • Overall, a good starter tank
Color: Color Fusion Size: 20 gallon
Good starter kit. Heater works just fine, filter isn't the quietest but isn't bothersome. I have the tank in my home office. Tank holds water and looks good, slight damage inside the tank rim where the filter sits. The plastic rim is broken in a four inch piece but is still attached, I will fix it with silicone. Light is nice, not super bright. The provided hood clamps when fully installed, cause the lid to flare up on the front and not truly close. Overall, not bad for the price. The hood and damage are my only real gripes. ... show more

    • Great product!
Color: Color Fusion Size: 20 gallon
Excellent deal considering what it comes with, I couldn't find any other kit that came with as much stuff! I did buy 1 more plant and a hiding place for my ghost shrimp. Some one said the plants look fake, but they are supposed to as they are part of the "Wonderland " series. That being said I'll admit they look good under they changing light colors. The filter is great and it provides plenty of water movement and it's pretty quiet(it was noisy for the first 30 seconds until it worked all the air out of the turbine), the only noise to come from it now is the water cascading off of it. The heater seems to work good, although I purchased this tank as an upgrade for my 2 goldfish so I don't use the heater in this tank. I use it in their old 3 gallon fish tank with a betta. It keeps the water at an even 77 degrees F. I would recommend as some add ons; gravel, some kind of starter bacteria to cycle the tank faster, some more plants /decorations, and more water conditioner/food after the samples are used up. The instructions for the hood do say to clip the lights into the hood, but these lights (at least for the color fusion) are a different type that come with their own instructions which is easy to install and one that I prefer so when I open the hood I'm not blinded by the led lights. One other thing I would recommend to get if you don't want to wait to add fish is nitrifying bacteria such as marineland's bio spira that should cycle your tank in <48 hours. ... 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

    • 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
