Hello, I am 100% set on a pair of ocellaris clownfish for this tank and I’d just like to know if I can add another small fish. I have a ton of copepods that aren’t a good sight (I didn’t add them) and can always in plain sight or on the back glass eating some small algae that won’t go away. I also have other pests like bristle worms and spionid worms which also occasionally climb the back wall. Is there a wrasse or a predator for these pests that I could add?
