Need some help

[vostasf]

Okay so I think this is my final version of the stocking list but I just have some questions towards the angel maybe being aggressive and what should I add first and when I should add all of the fish to the tank or if you would change anything

Thus list is for a 40g

Angel and clowns at the end

Also I much prefer a single clown. They are much sweeter. Also more diverse and abundant snails and crabs. I'd get everything in but the clowns and Angel. Wait a couple months , Get all 3 small and throw them in.

What would you recommend for my tank for snails and crabs and how many of each
