Review on 🐠 Enhance Your Fish Tank with Senzeal 2X Crystal Glass Aquatic Plant Cup Pot – Complete with 4X Suction Cups for Stunning Aquascape by Christine Green

I have one of these in my 5 gallon sandy substrate aquarium. I filled the bottom of the cup with some rocks and am using it for some small Yavana plants. My only complaint is that the mugs had a terrible smell upon arrival. That's what you expect from plastic, but not from glass. I just washed them and let them air out a bit before putting them in the tank. Otherwise they work fine. The suction cups adhere perfectly when placed next to a sponge filter, so the water flow doesn't affect their adhesion. I would recommend them to anyone, especially those with a smaller tank and therefore limited floor space.
