## Customer Reviews

### ⭐⭐⭐⭐⭐ The Betta loved it
*by J***S on January 16, 2026*

Very sturdy and comes with a way to truly hold it well. My betta loved it instantly .

### ⭐⭐⭐⭐⭐ Works great looks great!
*by D***E on December 13, 2025*

Got this floating island for the negative gravity chamber in my fish tank and out a glow in the dark moon sticker on my auto feeder behind it.. Reminds me of avatar! Looks awesome! 😎

### ⭐⭐⭐⭐ Fits my tank with a plastic lip - not the highest quality of material
*by P***G on January 23, 2026*

So it does fit my standard tank with a plastic lip - barely. And it is a functional thing, but the quality of the materials is a bit shoddy. Its clear acrylic and the supporting pieces have some pretty big air bubbles which is a little concerning. It does sit crooked in my tank, not sure what to do about that. It's a little challenging to install but that might have user error. Overall its worth it for the novelty factor.
