Leak from lid
Color: Clear
I do love the design of this aquarium! I switched out the filter and it looks nice in our living room. My only concern is it does leak on the left front corner. At first I was afraid I had a leak but have noticed several other people have posted they have the same issues. I do like the glass half lid but find it unstable when I am trying to feed the fish. ... show more

Lack of replacement options and missing dimensions
Color: Clear
Terrible customer service, i needed the canopy replacement, they didn’t even want to help me getting the exact measurements, thickness etcThe canopy on this aquarium is difficult to replace if damaged. The product listing and documentation lack key specifications like exact canopy dimensions and glass thickness, making it nearly impossible to source a proper fitting replacement lid. ... show more

Very nice!
Color: Clear
This tank is so nice, and sounds silly, but it's attractive. I get lots of compliments on it. The light has three settings which is nice. My axolotl loves his new home.

As expected.
Color: Clear
Bought this for a five year old and wanted to get the best aquarium so he wil have it years to come. He was so excited. Mother sent me a text. said Cooper said a prayer in the car headed to day care. He said "thank you Lord for my fish and for Johnny too". Lol.
