I just got a green mandarin and wasn't sure if I had enough copepods in my 115 gallon reef tank to sustain him. I ordered a jar of them, I think it came with 500-700, to add to the tank. How many should I put in and will this harm my set up? Also hwo can i store the extras and what else will eat these copepods? I do not have a refrigerium by the way. Thanks!
