Food advice (Hikari)

Hello!

Since Hikari is a brand we can't find here in Belgium, I am considering ordering some online, for all of my needs, for all of my tanks, and I was wondering if anyone could advise a type of hikari for each of them!

I'll try to guess, so if I have everything right, there will not be much work to do. ;P

Jardini Arowana (20cm?): Jumbo carnisticks / Tropical Food Sticks (Not sure the latter would work, if it does, it'd be great)
Oscar: Tropical Food Sticks
Potamotrygon Histrix: Massivore Delite / Sinking Carnivore Pellets (Chances are it'll need fresh/live, but worth a try)
Jack Dempsey: Tropical Food Sticks
Polypterus Delhezi/Senegalus: Massivore Delite / Sinking Carnivore Pellets
Rainbow wolf: Massivore Delite (???)
Channa Pleurophthalma (When I finally find them!): Jumbo carnisticks / Tropical Food Sticks

No chance to move my Bleheris to pellets now, but most of the above are young enough that I think they can be converted...

All advices would be greatly appreciated

Glad to hear, so I understood the basics at least

Ultimately, what would be better for Channas and Aro, The tropical sticks, or the jumpo carnisticks? if I am to get the bio-gold for the oscar and JD, those two are stuck in both categories, not sure which works best.
