Adding Clowns

[Noj]

Hello, I want to add 2 clowns to my tank once it has finished cycling.

Preferably they'd be mated or soon to be mated. Would I run into any problems of adding both clowns at the same time? Ammonia, nitrite, nitrate, etc levels jumping again?

Right now I am only on day 16 of the cycle and my ammonia peaked 1 week ago, and now my nitrites are peaking. Ammonia reads below .025 right now.

I have about 30lbs of live rock (fully cured), small amount of live sand (from established tank), and a few hitchhiker snails, hermit, and some type of starfish.

I am hoping that sometime around the 2nd or 3rd week of April I will be able to add the clowns, but I just want to know what I should be aware of before hand.

Thanks
