What type of food best for Corys?

I have 4 little bronze corys - who are absolutely great. They are in a 10 gal with a male betta.

The betta chases them from time to time, but there has been zero damage done over the last 2 weeks so I think it is safe - the corys are too fast LOL.

My problem is that the betta eats everything I put in the tank - and try to eat it all before it hits the bottom. I went to one of my LFS and asked what I should use - and was given algae wafers.

I looked around a little and decided that I would take "freeze dried tablets" Tropical fish food. They seemed interested in it - but then again they are Corys - everything is interesting.

Should I be feeding them the freeze dried formula (bloodworm, brine shrimp, tubiflex) or go for the veggie algae wafer?

Sorry - just learning about Corys and thought this would be the best place to get a straight answer.

Thanks.

Thanks for the advice everyone -

I didn't know that hikari made wafers. I feed hikari frozen bloodworm to my BGK. I was told that they had great quality and from the way he is growing, I'd have to agree. I will have to keep an eye out for them on my next shopping trip.

What other veggies do they like? Zuchini is not something that you usually find at our house. Would Cucumber work? peas? green beans? broccoli?

I like to vary their diets and to watch their reactions when I introduce something new.
