    • I Really Like the Curved Corners
Color: Clear
This is SUCH a pretty tank. The curved edges look very nice. While I have a few tanks already, I’d say I’m still kind of a beginner in aquarium stuff. Setup is pretty easy. Plop everything in, plug it in, and you’re good to go and add water (not fish. Look up nitrogen cycle first.). For a beginner I think this would be a good kit overall. I will also note that after a couple of weeks, no leakage. I really like the enclosed filter casing. I just personally prefer the way that looks. Additionally, the filter cartridge holder has a clip for a heater, which helps it also hide in the tank as well. While I don’t actually need a heater for my stocking, I LOVE that. I prefer having the heater near the filter for water circulation, but I also am not a big fan of having a heater hanging out when the tank is more of a centerpiece. I’m not a big fan of cartridge filters, but they do work, and this no exception. Water runs through it just fine. I might consider using some sponge once the included media eventually starts to disintegrate, as the cartridges have to be rebought separately. The lights are I think my least favorite, but they’re still fine. I use primarily low light plants because that’s what I already have, but I do miss some of the more complicated options such as light intensity. Considering how much I like the aesthetic of the curved front corners, I might like to expand on the types of plants I have. I do like the placement and how they are built in though, so if the lower light plants grow maybe I’ll just get creative. I do like the lid as well. The lid is a two-part lid, with a front glass lid and a rear hinged lid. Using both leaves very little as far as gaps for any wandering mystery snails to try and leave by. There’s a small gap left in the hinged lid for cords to go through, but that’s about it. Personally, I’m a little concerned by the glass lid, as it does feel like it’s not super secure, but that’s because I have a cat who secretly wants to be a fish. I don’t think it’s much of a problem if you don’t have something like that though. Lastly, I like that all of the accessories and pieces of this kit are removable. They’re a good option for a beginner to learn with, but if you’ve got a handle on stuff and want to swap in your own lights/filter/whatever, you easily can. It is a little more expensive than some kits, but I would still say it’s a good value, and I’m excited to watch my snails do their thing in their new home once the cycle is well established. ... show more

    • Love It!
Color: Clear
4.75 Stars - as an opener. This is almost my favorite of my tanks (another 20g and a 30g), we'll call it tied for 1st w/the 30g tank. I LOVE the rounded corner aesthetic, it's a much more impressive feature once the tank comes alive, I can't help but keep coming back to 'elegant' as the primary adjective. 250$ isn't cheap for a tank, but when they come as a complete kit/package, those numbers make sense when juxtaposed to the prices of filter pumps, lights, UV in particular, heaters/chillers, etc. and it racks up fast. I cannot say I'm fully sold on the built in mechanicals of this unit - or any other - it's going to take some time in operation to see how problematic it is or isn't - that's the 1/4-star deduction; I'm going to be setting up an external filter pump system that will service all 3 tanks together so eventually any such issues will simply be nonexistent. I suppose I should include that I've no interest in the GloFish themselves, but the product line has so far been pretty darn good, I've certainly not been disappointed in their stuff. ... show more

    • For Starters & Experienced
Color: Clear
The GloFish Glass Aquarium Kit is a fantastic all-in-one package that makes entering the world of fishkeeping, or upgrading an existing setup, a vibrant and hassle-free experience. At 20 gallons, it’s a great size that offers plenty of space for fish to thrive while still being manageable for most homes. This kit is a standout choice for its comprehensive features, user-friendly design, and overall value. One of the best aspects of this kit is that it’s a truly complete kit. It comes with everything you need to get started right out of the box, including a seamless 20-gallon glass tank, a premium blue LED light stick that makes GloFish colors pop, and a powerful integrated filtration system. Not having to purchase these essential components separately saves both time and money, and ensures that all the parts are designed to work together perfectly. This aquarium is an excellent choice whether you're a beginner or an experienced hobbyist. For newcomers, it removes the guesswork of selecting compatible equipment, providing a reliable and straightforward setup. For seasoned fish keepers, it serves as a high-quality, stylish tank that can be a beautiful addition to their collection. The seamless, curved-front design offers a stunning panoramic view of the aquatic environment, a feature that hobbyists of all levels can appreciate. The GloFish kit excels in its ease of use. The integrated filtration system is efficient and quiet, keeping the water clean with minimal fuss. Setting up the tank is simple, with clear instructions that make the process quick and painless. The included LED lighting is easy to operate and creates a stunning underwater effect, especially with fluorescent fish and decor, making daily enjoyment effortless. Considering everything included, this aquarium offers exceptional value for money. Buying a tank, filter, and specialty lighting separately would almost certainly cost more.

    • Love this aquarium!
Color: Clear
Review Image by CK2 CK2
I am impressed with this aquarium. The rounded edges give it a nice, modern look. The pump and filter are neatly housed in a slim black plastic box that has a built in hanger on the back of the tank. This is a clever design that not only keeps everything neat but also makes it less visible - no more having to strategically place plants and decorations to hide them. The filter box has small holes that keep tiny fish and invertebrates safe. There are other thoughtful design elements that make this aquarium kit stand out from others such as a built in clip to keep cords organized and a separate glass lid to make accessing the tank easy. I highly recommend this aquarium. ... show more
