6 gallon. So far about 4 months no issue, bought my own foam pad for it as the one they supply is very thin. Glass is super clear with a very slight blue tint. Good quality, no blemishes I’ve spotted yet. Currently a pea puffer tank after I used it for a QT tank

The clarity is absolutely worth the money and being rimless makes a huge difference. It comes packed really well, so I can’t imagine it arriving damaged. No leaks, and seems every bit as sturdy as rimmed aquariums. I’ve seen complaints that low-iron glass scratches more easily. I think that might be slightly true, but I think it’s mostly just that the clarity makes scratches more obvious. Haven’t had any problems with the magnetic glass scrubber, but the plastic brackets the lid rests on have left scratches.

I ordered this to start a saltwater macroalgae/refugium display tank that will be plumbed inline with a 50 gal mixed reef tank. I just received the tank yesterday via Amazon shipping. And the tank arrived well packed inside a foam cushioned panel wood shipping crate that was inside a heavy cardboard outer box for added protection. So far the tank with it's included glass lid, looks amazing and all pieces arrived in perfect condition. I'll be updating as I go through closer inspections and water leak testing. But outstanding all around first impressions thus far. Thanks Amazon delivery service team for going above and beyond on this order. Edit: I was able to safely drill an overflow drain hole for my Eshopps with the included diamond hole saw with no issues. So anyone wondering it is not using tempered glass and it can be drilled. I did check beforehand using the polarized sunglasses trick with the lcd screen of my cellphone. ;p Outstanding quality tank!

This is a BEAUTIFUL tank! And it’s my first tank! I gotten my betta fish in here and he’s doing great as what I have seen! I think personally it’s worth the price but unfortunately, the lid that came with it was broken. (I think that may have been my fault from removing the tank from box. :,D) But the lid was a bit too narrow for my liking. And personally not a fan of the plastic on one side of the lid that it came with. But the tank is easy for me to set up for the aquascaping! (Only gave it a four stars cuz of the broken lid and the size of lid is not to my liking. Which is personally is not a big deal to me as I can get alternative lid options and I’m already clumsy enough and scared to drop the glass lid. D,: Regardless, the tank is beautiful!

21 days into owning this tank (15 gal option) and can say it is very solid and well made. I went to my local pet store and looked at tanks there after purchasing this and noticed how sloppy the silicone lines were and especially how thin the glass was. The shipping box was very well protected (inside a wooden crate) and easy enough to take apart to get the tank out. Lid sits nicely with good border space. I have a Fluval Nano light attached to the tank and the lid fits fine still with that on the back panel. Great value for your money, only thing I wish they did was the cut holes on the lid seem a bit sloppy with chips, would of been nice to have some rubber gaskets in there to clean up the edges.

CRUCIAL UPDATE: After a short 48 hours I walked past the tank and identified a pool of water. It is leaking from the back side panel connection. BE AWARE 21 gallon version! $200 for a leaking tank that was beautiful for a short time. I really like this tank size. It is super heavy and sturdy. My lid did not come broken and I truthfully love the style because it has room for my plants to grow out of it. The cleaning cloth is nice, it’s a big size and gets the glass squeaky clean. All that said my tank (21 gallon) did not appear to come with an actual mat. At first I was confused because there was a white fabric that sort of fit the tank but was short. I went back to the description and saw the mat that’s included (according to the picture) is black but I don’t have any black neoprene mat with my tank which is majorly upsetting because I need a mat since this is a rimless tank. So now I have to order a mat that fits the tank but overall the tank itself is gorgeous so far.

I love it; it is exactly what is described. I might come back and leave a pic later, but it is cycling + need to scape. (I'm also looking for a light that has decent timer or no timer, which is not easy) It's the only reason I've ever bought distilled water in my life because I don't want any minerals on the glass. lol It's gonna be epic! 10/10 would rec update: after using the lid a few times, I noticed that the hole in the top of it is not so smooth and almost kind of chipped. definitely not as smooth as the rest of the tank.
