In a LED Biocube 32 what would be a good clean up crew? I have 3 nassarius 3 snails that begin with the letter A I dont remember the name and 3 hermits at the moment. All are on the smaller side. I want to make sure they are going to do well. I have no fish or coral yet. All my water parameters are good according to my lfs except my calcium that is only 400. Need to know what to use to bring it up also. Thanks....
