How much live rock do you have? How old is this set up? I wont be the fish police but that dragonette needs a very established tank since it and the 6line wrasse compete for all the pods.
To answer your question, i ordered 2,500 pods for my green mandarin. I have over 125lbs of live rock in my 93 gal tank and have no fish in it. The pods are multiplying like crazy.
