Indoor Pond

[JOSH]

I'm just looking for some feedback on an idea I came accross while in Vietnam. I noticed that many people there keep fish in large ceramic pots and I thought it would be a cool idea for our entrance....

Do you think I need to treat the inside of the ceramic pot with anything prior to adding water?

I plan running a pond filter within the pot which should double for circulation & possibily building some kind of simple fountain for surface movement. What do you think?
