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 Laura Brooks

Bought 7 months ago because it looks cool and thought it would make a good terrarium. Then my daughter saw it - and my god we have fish!?! So we have fish. And we (I) learned all we could from the negative reviews: It's too small for any fish - even bettas need at least 3 gallons. It's definitely not big enough for a goldfish (which the pet store says needs a tank of at least 20 gallons). So I bought a fancy "nano" goldfish tank. Then I realized that the pet store is not joking. So I bought 20 liters. And filters and test strips (later a liquid test kit when I found out the test strips were vacuumed) and a gravel vacuum so I could change the water. The fish then outgrew 20. I just installed a 60 gallon tank and have spent over a thousand dollars in the past seven months. For this reason"tanks". ;-)
