Adding new fish-when?

Hi,



I have a 25 g tank.

3 clowns, 1 coral beauty, 1 scooter benny, 1 coral banded shrimp, 1 brittle starfish, 8 cuc snails, 8 cuc hermit crabs, 1 really big snail.



My tank was an established tank of 1+ years. Bought and transferred Sunday (5 days ago). Used the same water and filter medium to reduce any bad changes.



Water tests very good.



Anyways, when could I begin adding new fish and corals? How long should an established tank move setup cycle (that the right term to use here?) before adding?



Question sounds impatient. I'm wanting this new hobby to work....otherwise I would have just amaturely added. :)



Thanks!
