pot

I thought it would be easy to make a hole in my clay pot, but that wasn't true. Does anyone have any advice on how I can get this done?.. I tried to drill a hole so far, but failed.. Thanks

Would like to give my Rainbow cichlids their own little 'love-nest'. They are in a 90g community tank with some big driftwood and rock, so I don't have room to put various size pots in there. With so many of you currently or previously breeding these, what size terrra cotta pot should I give...
