i have a fire shrimp in mine , been there for about 3-4 months still rarely see it, unless my blenny goes up to it to clean or he sees food. if you want one to be "shown off" get a skunk, if your like me and have your mine set on a fire just be ready to pay twice if not 3 times that of a skunk, seen them as low as 35 to as high as 59 here, were a skunk only goes for about 25
