Intended Fish Type Betta fish

Holding this Tetra LED Half Moon 1.1 Gallon Fish Tank in my hands, I immediately noticed how sleek and compact it is. The half-moon shape offers a unique twist on traditional aquariums, giving a clear view from almost every angle.

Unlike bulkier tanks, this one feels almost like a decorative piece that fits effortlessly on a small shelf or desk.

Setting it up was surprisingly straightforward. The clear plastic design feels sturdy yet lightweight enough to move around easily.

I particularly appreciated the adjustable LED light—being able to position it above or below the tank gave me flexibility in how I showcased my Betta. The light’s brightness is gentle but enough to highlight bright colors, which makes the fish pop visually.

The canopy with the feeding hole is a small detail that makes a big difference. Feeding my Betta was mess-free, and I didn’t have to remove the whole lid.

The size is perfect for a beginner: low maintenance and simple to clean. Plus, the clear front panel provides an unobstructed view that’s perfect for watching your fish swim lazily or dart around.

While it’s excellent for Betta fish, I found that the small volume means you need to be on top of water changes and filtration. It’s a cozy little ecosystem, but not for long-term heavy-duty use without regular upkeep.

Still, at just $16.50, it’s a charming starter tank that combines style with ease of use.
