Yea, I bought a pair of swordtails yesterday and put them in my 40 g. They both kept on coming to the right side of the tank, which the angelfish has claimed as his territory, so he kept on threatening them away. Well anyways, I wake up this morning to only 1 fish. 
I'm like WTF!!!! I search everywhere in the tank and around the tank, behind my cabinet and all around. Nowhere. 
Where is my fish? I was hoping to have them breed in my tank. And the sad thing is that if I found it dead in my tank, I would be totally okay, but if it's sitting around my living room rotting.... I'm in deep sh*t. Someone please tell me I have a special species of swordtails that can go invisible. Please tell me I have this special fish.
BTW, Deathsting lovin' the new gulper setup!

I've quarantined the guppy for now in order to relieve some of the harrasment of the male sword. I'm gonna start looking for a female guppy and see if she will take all the attention away from the male swordtail. I will also be searching for another female sword for my male, because I want to try and get some longer swords on the offspring. And now I think that it is time to put on that back piece of plastic on the cover, so I will be placing that on as soon as possible. 
here's what I picked up:
