Is the butterfly eating?
That is a xanthurus not a mertensii...
yep
first 2 days he had a hard time with a yellow tang in the tank but he seem very comfortable right now. Nipping on rocks and eating whenever fed.
I make my own frozen food with a mix of fresh tuna and seafoods (mussels,oyster,shrimp,squid,venus clams), dried cyclpoze, phytoplakton, frozen cyclopeze, zooplankton, "petlife" perfect food, arcti pods, "reef nutrition" rotifer diet, "two little fishies" marine snow, "aquavitro" Vitamine Fuel.
here my 3 newest additions
1 Mertensii Butterflyfish (Chaetodon mertensii)
2 Firefish (Nemateleotris magnifica)
Not the best pictures but you get the drift
