Hello ladies and gentlemen! Just started a 10g nano for my son’s room. Figured I’d go with a pirate-y theme so added a skull between the rock work, maybe attempt to have a lepto encrust on it like all the cool people are doing. I haven’t really seen any decorative prop pieces in the reef tanks, is there a reason it’s not a popular addition? And is a small HOB filter adequate for a 10g nano reef with maybe 2 appropriately sized fish and a few corals? Thanks!
