olde rocks

[leongreenway]

Hi, have some granite / slatey type rocks that i used to have in my first aqarium that contain 2 mexican walking fish. When they passed on several years ago i put the rocks in the garden. I would like to put them in my new tank. Do i need to prepare them in anyway. Apart from a good rinse.

I would treat is as anything that you want to stick in your tank: clean it in boiling water (unless it will melt if you do so), scrub in vinegar and then rince in fresh water... and you are good to go!
