So I went BB on my new 20g and I’m looking for recommendation on CUC members. It’s a drop off tank so I’m going to try to put some hermits up top and some down below. I may eventually try and bridge the two areas so they can go from top to bottom and back again.
				
			 
	 
 
		 
 
		 I stay away from snails that need me to flip them over.   And since your system is new, start with a few of each and then add more as you have more algea to feed them.  (in my 20 long I have probebly 5 snails and 7 hermits)  Once my tanks reach a year I always add a pincussion urchin.  The BEST in my opinion in keeping a very tidy tank... as long as you dont mind them eating your coraline too.  This is just my opinion...
