Neon Tetra possibly breeding?

I just went to feed my fish for the night and while doing a nightly head count I found one Neon to be missing. I looked all over only to find "her" hiding in the Cory's cave. Its being very still and not coming out what so ever. Nothing has tried to enter so I don't know if its being territorial. It has all its color and doesn't seem to be sick in any way. From online research on sexing, I've determined that most likely I have 2 males and 3 females. I can't really find anything on their breeding behavior. I just get " difficult to breed". Can anyone tell me if this is a possible breeding sign? I've included a pic but its difficult to see. Any help is appreciated.

Update: This morning I found her slightly tilted on her side in the cave. I was almost certain she was a floater only to get a message from my fiancee that she was out and about with the other four an hour or so later. She came out and ate fine tonight and now keeps swimming in and out of the cave. A majority of the time is spent in the cave. I look for eggs all the time because I read that the entire breeding to laying egg process could over rather quickly. What color would the eggs be if she were to lay any?

Most tetra, being characins, are egg scatterers. If the females are ready, the males will chase them and drive one into a thicket of plants. The eggs are expelled and fertilized, and fall among the plants. Being sticky, they adhere to the leaves. The fish in the aquarium, recognizing what is going on, will usually then devour the eggs as fast as they are expelled. The parents too, when their spawning frenzy is finished, will readily eat any eggs they find.

What you describe would seem to be some health issue. I won't even try to guess what. Monitor the fish's behaviours, and check for any obvious signs of causes. A partial water change often helps.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
