I know what you mean about being excited about the naso. I just love my Big Boy. They are the most beautiful fih. Any my fish is almost 100% vegan. Which I love because he's like me.
Anyway all he was eating was seaweed select (Ocean Nutrition) and a ton of Roman lettuce. He HATES BRINE, MYSIS, FROZEN FORMULA 2, then one day I bought live tubeflex worms and he went crazy, I have never seen such a sight, it was somewhaqt sad to me becuase I found out that he isn't 100% vegan. But I still love him. Anyway he also loves frozen blood worms.
Defintely give him SEAWEED SELECT AND SOME ROMAIN SOON, AND I BET HE EATS THAT, LET mE KNOW
