So Very Disappointed

I was so excited to order this, and it was delivered today. I didn't even open the box and I could tell it was completed demolished. Glass shards were spilling out

I was so excited to order this, and it was delivered today. I didn't even open the box and I could tell it was completed demolished. Glass shards were spilling out of the shipping box. I'm sure it would have been a wonderful product, but the maker and Chewy need to figure out a better way to ship fragile items so they arrive in one piece...and not in millions of pieces...

The tank is perfect for multiple bettas. I can adjust the pump so that there is little or high flow. I have noticed, however, that the betta in the middle tank was able to see the other two bettas through the cut outs but this was easily fixed by adding more plants so he couldn’t see them anymore. The packaging was ok but I would recommend that chewy have some label that says fragile on the box.

Unfortunately I am unable to experience this aquarium because it does not ship well. The first one had one broken pane and the lid was broken, the replacement was completely shattered. Unless this aquarium is packaged differently, it's guaranteed to arrive broken.

Great Tank

Clean looking. Flow on the outlet tank is a bit strong so I added an outflow sponge. Just bought a second one. I added some snails as well. Very large filtration

POORLY PACKAGED

This aquarium is perfect in every way. But it was very poorly packed. This is all glass with a glass lid, it is all in a thin cardboard box with absolutely no styrofoam or any kind of packing. . Mine arrive shattered in pieces. Even the light fixture was bent and damaged. Why would anyone package glass this way? It was not the fault of Chewy at all. It was the manufacturer and FedEx who mishandled it, Chewy immediately sent me a replacement but I am not too hopeful it will arrive in one piece. I will update when it gets here. Customer service is the best.
