Oxygen bubbles from the filter required?

[russrimm]

We just got our first quarantine tank, a 5 gallon hexagon from walmart. It came with an in-lid filter/pump. It doesn't put out a real fast stream, so I see no bubbles going into the water like I do on our 20 and 65 gal tanks. Is there still oxygen going into the water? Or should I be able to see bubbles?

Oxygen will still get into the water through contact with the air in the room. If your filter/pump just creates a little ripple at the surface, you should have enough circulation to oxygenate your water.
