Thanks I'll pick up that size, I do have some spirulina flake on hand already (I like to give all my cichlids a bit of veggies).
By small and somewhat delicate is this something that I should be concerned about mixing a 3" severum with? I'm sorry if I keep asking rather daft questions, it's just I never kept Angels before and have always viewed them as rather peaceful fish - like in the neon tetra area of peaceful...perhaps my idea is rather off on these fish though.
