Update- so I mixed the seaweed nori and macro on the clip today. And he tried to nibble the macro only but I think he got some bites of nori so I'll keep trying that.
Secondly when I fed the macro-meat mixture I swapped the macro for a herbivore mix today (insects, crustaceans, spirulina, brown Algae and veggies like romaine lettuce). Soaked all in garlic. I noticed something interesting today he had a feeding response chasing the food. He ignored the meat of course but he ate the veggie leafy bits, spat them out, ate them again, spat them out and repeatedly did that till it was tiny pieces he spat out then he left it there. Did this with a few pieces of leaves. What's the meaning of this? If my foxface wants to eat it he just swallows it whole.
Also his grazing habit is insane there isn't a blade of algae anywhere, he eat everything.
