They definitely would get outcompeted for food by the faster tinfoil barbs and barracudas.
I would look into dividing the pond into two and placing the discus in their own dedicated segment of the pond. You'll still have more than enough space for the discus and can have them get their share of food. Good luck with your leap into discus keeping.
