About Tetra

Tetra’s tradition of innovation started more than 50 years ago in Melle, Germany, where Dr. Ulrich Baensch founded the company (Tetra Werke) and pioneered the development of flake fish food - an innovation that revolutionized the industry. At the time, growing and harvesting food for your fish was a painstaking process. The advent of flake fish food not only made feeding your pet much easier. It opened the way for more people to own an aquarium. At Tetra, we’re dedicated to helping seasoned hobbyists and beginners alike enjoy a successful, life-long aquatic experience.

A very nice tank. Wide and tall giving fish lots of room to move around. It is a bit heavy and large so be careful moving it around.A full tank may weigh over 255 lbs so make sure you have a stand that can handle the weight.

    Went from 2 ten gallon tanks to this one for our 3 goldfish and I’m still incredibly happy with it. It’s been a few months and there have been no leaks or issues with the tank. The rim is still fine with no cracks or imperfections of any kind. I use paper towels to clean the inside glass when it gets icky instead of scrapers or sponges. They didn’t work well on my other glass tanks either anyway. My only complaint is now the fish are getting even bigger. Not the tanks fault. It’s a perfect tank and was the absolute cheapest I found after hunting for days (on and off Amazon). Highly recommend 5/5.

    I'm very pleased with my 55 gallon aquarium for my turtle. It looks great!

    If I had to nit pick at one thing, it would be the big bright orange sticker, that's located at the bottom and completely inaccessible. You're unable to remove it. If you're looking to have a clear bare bottom tank, you're stuck with looking at the bright orange sticker. Thankfully I have substrate at the bottom so I don't have to see it.

    Other than that, it's a very good quality tank. It didn't disappoint.

    Size: 29 GallonsVerified Purchase
    I've wanted to have an aquarium since I was a kid. This is much taller than I envisioned to be, I can see that may be why the specific unit I bought was a used/return - I'll take a deal price like that every time. The one complaint I can lodge is the sticker stuck fast to the bottom inside, it'll be a nuisance to remove. Besides the discount price, the 18-inch height was one of the main reasons for choosing this one, more viewing area and a taller water column generally, for more potential activity. It's really not as heavy as one may think, but it is a touch awkward to handle given the dimensions. This is a relatively large volume of water, so it'll be heavy - one must account for that. I'm setting up a multi tank system with this as the main body, a 7 and this as 28 make a solid 35 gallon to work with. This is tempered glass, so it has the extra strength to actually support the weight of a small(er) tank sitting on top; although I'm pretty sure it'd hold up to it, I'll be fashioning a stand of sorts to help augment for strength of structural integrity. Describing it isn't much help, I know, so I'll add some pics to this review once I get it up and humming. This tank came with a couple packages of tank treatment 'stuff', which is at least a clue/notifier of the need to treat tap water, if not on a well - which I am. This is just a tank without any components, not a kit - although that is clear on the page data. The 2 "main" differences in tanks are the rim/rimless configuration; I'm adding a negative pressure tank, or 2, also - but both of mine have rims that will need modified to accommodate it/them - I want at least 1 on each tank. If my modification works, I'll definitely share it and include in this review as an edit. Besides just getting to finally take up a hobby of great interest, I'm also hoping this may become a potential "side hustle" of sorts, there's some species of fish and invertebrates I want to breed also; this tank has sewn seed for lot more than just this one.

    I bought this tank and after 1 week it started leaking from the bottom panel. I had Amazon send a replacement and after 1 week with the replacement it also started to leak from the bottom. Amazon would not send a second replacement (not that I wanted to purchase this tank AGAIN) and i had to argue over the phone with them to even get a refund on this product so that I could go find another tank from a different brand. DO NOT BUY THIS if you value your animal’s life. My axolotl has been through a lot already and this has added even more to his stress. If you need the tank for something that does not require water (reptile/rodent), it would probably work but even then I would be wary of giving this company your money if they don’t care enough to craft a quality product. I mean they literally have 1 job and that’s to hold water and they can’t even do that so beware.
