For any of you who remember the hit Disney film ‘High School Musical 2’ and enjoyed it as much as the first or found the songs catchy, this week’s Fish of the Week could be the marine for you. With a Hawaiian name of “Humahumanukanukaapua’a” (a song from the film which I’m sure you’ll remember), the Picasso triggerfish (Rhinecanthus aculeatus) is an easy-to-care-for favourite for many marine aquarium keepers. This large fish originates from the Indo-Pacific and can grow to around 25cm, so make sure you’ve got a large tank. This fish is an avid eater of pretty much everything it encounters, so shouldn’t be kept in a reef tank or with small fish or they can get slightly aggressive. If you’re prepared to put up with its quirks regarding its home and its neighbours, however, the Picasso triggerfish is a highly entertaining and active resident, blowing jets of water whilst searching for food, ‘gargling’ sand and silt whilst searching for food, and are quite clumsy often knocking things over whilst – you guessed it – searching for food! This hungry beastie is sure to put a smile on your face, its bright colours mean you’re unlikely to miss it, and it’s therefore our Fish of the Week.
