I have a IM 25 gallon lagoon tank (dimensions: x 18 ×12) Currently I have a starry blenny and a banggai cardinalfish, absolutely zero aggression between the two. I think I want to get a pair of panamic barnacle blennies, would there be any aggression between them and the starry blenny? My rock scape has plenty of crevices and I plan to add a barnacle cluster for the panamics.
