Thanks for the ideas, guys.
I did think the recommendation was a little odd. I have a whole host of foods at my disposal (several flakes, several pellets, several types of frozen, Arctipods, nori) . . . but I'm supposed to feed veggies? Peas and zucchini appear to be very popular with the FW folks.
I'm not sure why either of those would be any sort of appropriate, natural, species specific diet . . . for anything other than my Holland Lop rabbit (versus my Foxface Rabbitfish).
