just be careful later on when you're adding anemones. clarkii is known for accepting any anemones. and you know how clownfishes are with anemones, they will defend them so bad that the clownfishes might harm others. mine bit my cleaner shrimp's antennae and cut it off when it's trying to steal the food from the anemones. so the perc might not go to the clarkii's anemone but the clarkii might. just be careful. those two in a 100 gallon should be just fine.
