The 3N tank fits perfectly on my nightstand. The clarity is excellent and the mitered edges look clean. The included leveling mat made setup simple. I’ve added a few dwarf shrimp and they’re thriving.

I bought the 5N size for my living room console. It’s compact but still gives a good sense of depth. The glass is very clear and the German silicone seal feels durable.

Handcrafted quality is evident in the finish. The laser etched logo adds a nice touch. I used the black nano-foam mat and it keeps the tank stable on uneven surfaces.

Great for small spaces. The 3N fits well in a corner of my office. I like the minimalist design and the lack of rim makes it look more modern.
