Christopher ★★★★★

Set this up on my desk next to my monitor and the LED light makes the whole tank glow without washing out the plants. My betta seems way less stressed in the 20cm footprint than he was in his old bowl. Only thing is I wish the light had a dimmer, but honestly for the price it's hard to complain.

Sofia ★★★★★

The glass is genuinely crystal-clear, no distortion even when I look at it from an angle, and the LED light makes the whole setup glow nicely on my desk. I've had it for two weeks now and the seams are still invisible, which is more than I can say for my last tank.

Christopher ★★★★★

Tiny but mighty — the 20cm footprint fits perfectly beside my monitor without cluttering the desk. The LED light tucks in cleanly and makes the crystal glass edges glow just enough to notice the water clarity after sunset. Setup took under five minutes and my betta seems to appreciate the calm, brig
