This is a lovely aquarium with lid rounded front for better views acrylic so won't be heavy has a little hole for feeding that also is helpful when wanting to lift up the lid The size is great for a Betta fish (please don't keep Bettas in tiny bowls. One gallon or less "fish tanks" are NOT suitable for any fish... maybe for seamonkeys LOL) I have a few little extras that can come with it like a bit of gravel for substrate (it is good clean Marina brand) and an aquarium fake plant capacity for this cute fish tank is around 3 gallon ( almost 11 and a half litres )
