So yesterday my wife and I went into lfs and she found what she always wanted a tiger pistol shrimp and a yellow goby. So the shrimp tried to make a home for himself where my dottie back lives it worked overnight but today he found himself out on the streets. The rest of the fish won't let him or the goby next to the rock. So they paired up and buried a ditch under my conch lol. I have a bunch of dry rock but don't know if a few pounds of it will harm nutrients. Would I be able to put some in there to build them a home or should I wait and pick up some live rock from lfs. I know once the conch moves they are going to be in the streets again. They look so cute up under there. Thanks guys
