Help! I had hitchhiker Fry/eggs? Possible?

If you would like to skip the information, I placed the more "to the point" info in bold.
I noticed last night that I had a lot of larger white specs floating in my tank. So I spend some time to investigate, and noticed that they were larger than a copepod, and were definitely swimming, so it was not some sort of contaminant, and I presumed at first that they were a jelly fish because I had finally identified Hydroid Jellies on the glass of my tank. And I figured that maybe they had left the glass, and were now swimming, because I had not seen hardly any on the glass anymore. But then I turned my lights back on, and noticed that the little specs had eyes, and what appeared to be a body, and a large fin that went from behind the eyes, to the underneath. They are clear/white like a copepod, and seem only active at night. I caught 2 and placed them into a container so that I can monitor them, and placed the container into the back chamber next to the pump and heater, so as to keep a consistent temperature as the tank.
I added a large range of rotifers and plankton to my tank and a small amount to the container this morning. I also placed decapped brine eggs into the tank, and a drop into the container, was that okay? I know the decapped eggs won't harm my corals nor my other tank mates, so I was not too worried.

I also would like to add that I noticed them after I received my order from BlueZoo Aquatics, which consisted of 1 Pistol shrimp, 3 Pom Pom Crabs, 1 Emerald crab, a six line Wrasse, and Yellow Rose Goby(both fish are in a 10g quarantine tank) and a "Mushroom Grab bag" I received for free due to my purchase price.


Okay, to start off with tank info, my tank is relatively new, about a month and a half. I have biocube 29g, with the standard pump, live rock and sand, a protein skimmer, and I currently only have reticulated foam, and carbon. I have no circulation pump.
Livestock:
1 Pistol Shrimp
3 Pom Pom Crabs
2 Peppermint Shrimp
2 Emerald Crabs
Assorted hermits, most dwarf white leg hermits
Nassarius and Cerith snails
I also had hitch hiker vermitid snails, as well as some stomatella snalis.

I know that I have quite an abundance of Copepods, my water column is normally swarmed with little white pods.

I had a piece of blueish purple clove polyps and some meteor shower cyphastria I placed in the tank that have been in there for about a week or two now.

Water Parameters:

Ammonia: 0
Nitrate: 0
Ca+: 420
KH: 8.5
And that is all I can remember from the test I did last night. If any more water parameters are needed, I can get them, just ask. I use the API test kit for Ammonia and Nitrate, and then the Red Sea titration kits for the rest.

0 nitrates? Are you sure you don't mean nitrite? Zero nitrates is bad.

Well, if you have zero nitrates, that's usually an indication that the tank isn't cycled completely. The nitrogen cycle goes ammonia -> nitrites -> nitrates, so you should end up with nitrates if all is well.
I suggest testing your water again. Unless something is consuming the nitrates, something like a macroalgae, there should be some.

Zero nitrates is good, yes, but sometimes it's a sign that the cycle isn't complete. Check to make sure you have no nitrites. If no ammonia and nitrites, something is eating your nitrates. That's good.

Not sure. Can you get a close-up picture of the ones in the container?

Hmm, yes, that would fit.
In other terms, that means they're uber-baby crabs or shrimp that are still in the plankton instead of crawling.
