Review on MeiBoAll Wall Fish Bowl: Clear Acrylic Betta Fish Tank with Wall-Mounted Aquarium and Plant Pot Decoration - Set of 2, 230ML Each by Nick Narvasa

They hold exactly the same amount of water as the Beta bowls sold at most pet stores which was disappointing as I thought they were a bit larger. with a hook that has 4 tiny nails that basically already go through the plastic hook to be driven into the wall - but at least the nails are very small, flush with the surface of the hook when driven into the wall, plus none of the nails and a large part of the hook is not visible when the wall tray is standing on it. I decided to buy them for kids rooms and they love them.
