Review on Umbra 460410-660 FishHotel: Unique Glass 2 Gallons Mini Aquarium Tank Bowl for Goldfish, Betta, Glofish, and Small Fish - Perfect Home, Business, and Birthday Gift Idea - White by Crystal Mack

Shame on designer Teddy Luong, who continues male cruelty by designing an aquarium too small to achieve optimal male health and satisfaction. And shame on Revain, as well as Petsmart, Petco, and other retailers who sell these and other ridiculously small containers they call "Betta Homes." People assume they're acceptable if they can be bought, but they're not. If your Betta is not active (and obviously cannot be active in a tank this size) and if he is not blowing bubbles, he is neither happy nor healthy!
