Ultra-High Transparency: Betta fish tank is made of ABS, smooth and burr-free, and the inner tank is made of AS, with ultra-high transparency so that you can observe your beloved pets up close and feel their growth

Independent Space: You can use this small aquarium to create an exclusive space for one small pet like a betta, hermit crab, jellyfish, turtle, tarantula or another, which is a private place that they don't have to share
