Sand Sifter Gobies & Deep Sand Beds .. friend or foe?
Is it a good idea to add a diamond watchman goby to my 72G reef. I have about 3" of sand, I know it's less than the 4" recomened for deep sand bed, but I can see gas bubles in the sand, which should be a sign the denitrification is going on. I also have about 100G of live rock, so I'm probably getting the rest of the denitrification from there. The reason I wanted to add a sand sifter is that I'm starting to get some patches of algae on the sand. I wasn't sure if the goby will completly wipe out all my sand critters in that size of tank. And if it does, will the fact the the goby is stering the sand still keep the precess going anyway? or will he stir it too much, that the sand will be too oxiginated and denitrification stops. Is it better to get a two spot goby instead, they seem to be smaller in general?
