Once you start you will have to keep doing it, its like opening Pandora's Box you don't know what you will release specially if it is a deep sand bed. I made the mistake of getting a Yellow Head Gobi well I could not even try to comprehend what an Engineering Gobi must be callable of after seeing what my Yellow did and then shortly after I pick up a Pistol Shrimp and WOW the tunnels this guy builds amazing. I did pay a price though, my Nitrates started to climb high and fast and my Phosphate with it, ever since I have be in battle with the two. Hair Algae should up and Cyano and Bryopsis. It has been a long Battle and still going.
Bottom line I am just saying, " if you have not you maybe you should not ".
