Last Guppy Standing

So my last giant guppy decided to follow her comrades to bid farewell to my tank. She did not look too well for the past week and I've tried all possible ways to "heal" her but with no avail. She finally decided to call it quits this morning and she is still floating in the tank now ... why? Well, I'm waiting for Bryan to wake up so that he gets to "scoop" her out and take her to her resting place. Funny thing is that the other fishes in the tank does not seem to mind her floating in their home.

Now, we're left with only the small female guppy which I've been trying to hard to cross breed my male black bar endler but that does not seem to be going anywhere. I've finally found 2 individuals that sells the endlers as pairs but one of them require me to buy a few pairs and I am not sure I am willing to part with that much money for this hobby yet. I'm still waiting for a response from the other person ...
