Help! Guppy Fry!!

So about a couple months ago, I got a few guppies from Petsmart. I didn't think to sex them because I'm still fairly new to the hobby. Fast-forward to two days ago, I noticed my guppy was a bit more bloated than usual and it had a dark spot just in front of the anus. At first I thought it was dropsy (its scales looked like they were sticking out), but after a few hours of researching I looked at her from the top (after a suggestion from a youtube video) and noticed that its scales weren't sticking out. I got back on my computer and had a passing thought that maybe the guppy was female. I looked up a couple diagrams comparing the two sexes and what do you know? She was female! On top of that, she was PREGNANT! The next day, I rushed to the store and got a 10 gal. QT tank to let the guppy give birth peacefully. I set it up yesterday, put 40% new tap water and 60% water from the same tank she was from. Today I woke up, but she was dead. I assumed all her fry died with her, until I found one. So my point is, I've never had any type of fry (guppy or otherwise) and I have NO idea how to take care of them!! Please HELP!

 

Is the 10 gallon qt. Cycled? If not I would transfer some of the filter media from the main tank to the 10g to help cycle it quickly. For baby guppies as long as you can get some live plants (I would suggest Marimo moss balls or Java moss) and you’re able to feed it some crushed up pellets or flake food it should be fine.

 

I have a sponge filter in my 5 gal. tank, would that work?

 

It probably isn't cycled
If you want to cycle it fast get a cycled sponge and squeeze all the nasty stuff into the tank and that will cycle it faster.

Is it okay if I use the 5 gal. filter as a permanent thing?

Yes, and it should bring over the beneficial bacteria too. I would eventually upgrade to a 10g filter if you want to add more fish but a 5g filter should be fine for guppy fry.

 

If you have another filter in your 5 gallon tank and you keep something in you 10 gallon to keep it cycled then yes. I have snails and shrimp to keep my qt tank cycled

 

Okay, thank you so much, I was panicking a bit there!
It doesn't seem to be moving around much. It mostly just lays on one of the decorations I have or darts around. Is this normal?
