8 day vacation

[FoxiiiC]

I will be going on a vacation for 8 days, and currently have 4 male guppies in a planted tank. Would my best option be to get a timer that turns my light on and off, and should I also get a feeder for them?  Unfortunately I do not have anyone who can feed them for me and I worry that the feeder will cause issues, so if anyone has any recommendations on ones they know to work, that would be great.

Buy a timer for lights.  Here are some great videos to help you prep and set your mind at ease. Guppies are amazing at finding things to eat in a seasoned tank. 
ACO also makes a good autofeeder if you choose that route. 
Enjoy your vacation

That being said, I personally think 8 days is kinda long. Also how seasoned and planted your tank is, whether there is any algae, biofilm and critters, and how healthy the fish are could play a role on that one.

I would personally obtain an auto feeder. I have one at home to use whenever needed. You can buy it once and use it whenever.

If you can't have someone feed the fish 1-2x during the separation then I would either avoid food during that time (fish will be fine) or go ahead and use something like repashy right before you leave and it will give them food for a little bit.  An autofeeder is also an option.

As for the lights....

I would honestly just leave the light off and call it a "blackout" of sorts.  Depending on what is going on with regards to you plants and their needs, if you have any sort of algae issues it would just knock the algae back a little.  I just mention it as an option.  There's no harm in leaving the light off. 

The videos above are a great reference and it's awesome to have things like that to point people towards.
