I noticed that it appears that your clown hosts in your frogspawn. I have the same exact situation. Same variation of frogspawn with a false perc. Have you ever noticed any ill effects from the clown on the coral? I noticed that when it first began, the coral dropped all of its tentacles and was basically just a green ball. They have since regrown as this was about a year ago, and now the coral has split and is in the process of growing 4-5 new heads. Have you ever seen any damage from the clown?
