Regal Tang Paracanthurus hepatus (also called Blue Tang, but I prefer to not use this name as it could create confusion with Acanthurus coelestis, the (Atlantic) Blue Tang), two Yellow Tangs Zebrasoma flavescens, a Longnose Butterflyfish Forcipiger flavissimus (not to be confused with F. longirostris, similar and known by the same common name but differs in having a longer snout), and a clownfish species Amphiprion sp. (either A. percula or A. ocellaris, would need a closer-up pic to confidently say which)
