    • Large aquarium is good for what I bought it for.

Works well for what I got it for (Two hermit crabs). Came with a tiny bit of fish food and a guided manual, but alas, I don't intend to house fish for a while (not until I clean my office, anyways!). This came in its own box and had a lot of foam to hold the corners. It was heavy inside the box, but outside the box it was somewhat more manageable. It's just getting it out of the box that was my biggest problem, although I was trying to be quiet as a mouse doing so. It's definitely large, large enough for 6+ inches of sand-coconut substrate mix AND decor. The price was steep, and I'd have probably been better off searching for hand-me-downs, but I wanted something clean. So far, it does not leak and keeps humidity in well when coupled with a glass lid. BTW, it doesn't come with a lid - I bought my glass lid seperately. Looks clean without any marks and is very sturdy. ... show more

Delivered on icy driveway. It unpacked in minutes and was set up within an hour. Great job! We lost power for a week and all the fish died. Then the old tank leaked out several gallons onto the carpet. Now we need fish.

    • Very nice tank
Size: 29 Gallons
I havent filled it all the way yet but so far its a very nice tank and a good size. I now know i would prefer a wider tank, not the tanks fault as this is my first aquarium, but the 12 inches wide is a little smaller than id like, perhaps 16-18" would be better, but again no fault to this aquarium. I like it and would buy again! ... show more

I got this for my partner for Christmas and it’s a beautiful tank. It’s sturdy and does not leak. It came all assembled and is very easy to clean. We bought a stand to go with it and it fits perfectly on it.

Very nice. My little guy(Fred the turtle) loves it. Maybe I will have to get a bigger tank. 😁

    • Oooh La-La!
Size: 29 Gallons
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. ... show more
