Good tank, be wary of the filter

I ordered two of these tanks a few weeks ago for my new house. I went to set them up long before the move so they could hopefully cycle by the time I’m ready for fish to be moved into them. They looked great when I first set them up, but when I got back a day later there was water all over my floor. I assumed it was a leak since I hadn’t checked if they held water before I set them up. I emailed chewy, and since they’re amazing, they sent me two more. They got here within two days, and I had filled both of them with water and left them for two days before I actually set them up to make sure they didn’t leak. Everything was great so I added the decor, got the filter and heater set up etc. luckily for myself I went back again the next day to double check they hadnt leaked. When I walked in and saw water all over the floor I almost screamed. After some further investigation I finally realized that the filter was overflowing out the back and that is what was causing the tanks to drain. So while I really recommend these tanks, and I think the price for this kit is super worth it, I wouldn’t necessarily recommend using this filter. But the tanks themselves are gorgeous rimless aquariums, especially for the price!

Fish tanks

Fish tanks leak constantly....almost lost both my bettas. Never figured out why this kept happening...turned the tanks into terriams and bought new tanks.

Very nice tank

I loved how simple it was to set up. Great for beginners as it comes with a filter and a light. Suitable for one beta fish, or for some shrimp. Does not include a heater, so be sure to add a small one! Just set it up, cycle it, and your ready to go. Simple & stylish.

Not fond of!

The tank is made of all plastic & there is no cover for the feeder, I had to tape all sides down . Plus the lid remaines full of due and there is a large gap where the filter goes that I also had to tape over so my beta doesn't escape.

Perfect for smaller fish and shrimp!

I bought this tank to keep my shrimp. It is the perfect size and comes with everything you need to start. Great for a nano tank or for a single smaller fish!

Filter overflows

I use this tank for my betta and it is a really nice set up but the filter over flows and causes water to spill out the back of the tank. I came home to water all over my floors and on all the shelves of my stand.
