Yep it's a bowl but still a great find. It does come with more than a goldfish.
Anyway, I do believe the aeriation of these bowls are not so good.
How would I know, I'm not a fish!
I've noted that BiOrbs have received quite negative feedback in the past, so I was interested to see what this one would generate. I have been looking for a fish tank for my Son, and my research suggests this is a good deal. However, that is not to say that the BiOrb is the panacea of all fish tanks but this deal does open up the BiOrbs to the bottom end of the market!
As far as whether these 'bowl's provide a good environment for the fish I wouldn't have a clue, though I suspect that a fish would argue against being confined to any fish tank given the choice!
