Ceramic Bowls With Lids Is My Current Cage Okay For My Robo Hamster?

Is my current cage okay for my Robo Hamster? - ceramic bowls with lids

I) a 10 gal Kritter Keeper (aqauriam plastic lid with colored plastic. I have a small ceramic bowl, mini-bikes, mini igloo, and the role of toilet paper, not much room to run, but still scratches on the corner of the cage. I want them to have a space for robbery hamsters, are stronger. Should I, a 20-liter tank for fish? Or is it too big. Thanks
