when to add invertebrates

[JOSH]

when ammonia nitrates and nitrites are all at zero, usualy 3 weeks, depending on your rock, if its cured live rock you can add then alot sooner

also to note, Cleaner shrimp and other inverts similar to them are classified as harder to keep in the way that they do not deal with fluctuations very well. crabs and snails wait until there are no immonia, nitrates, or nitrites. I have lost a couple cleaner shrimps and a blood shrimp and not lost fish because of an immonia spike.
