Hello, I had a Sebae Anemone in my tank but my clowns would NEVER go to it. Unforuntetly, it died which I heard is fairly common with this type of anemone. Now, I want my clown to host something, but what will it host? I have a perucla clownfish in a 20 gallon tank! What kind of corals will host the fish? Thanks so much!
