Tankmates for Guppy Colony

[Shazoom]

Hello all!

I have a 20 gallon long that I have been breeding guppies in for the last 2 years. I have a steady colony going that maintains numbers by itself. The tank is heavily planted.

I would like to add some tankmates that won't totally obliterate the new fry population. For some reason, my guppies don't eat their fry. Almost all of them make it to adulthood. 

I have a single beckford pencilfish in a different tank, can I add her and a few more pencilfish to the guppy colony? What are some other good tankmate options in this case?

I'm also thinking of a few julii corys! 

Thanks in advance!

Shrimp would be a good choice, the corydoras would be fine as well.

Pencilfish have such small mouths that I bet most guppy fry would be fine.

Green neon tetras have been a great addition to my guppy and swordtail tank. But I would also second @T. Payne's recommendation. Cory's seem to go with anything, as far as I can tell.

When I had a guppy colony I loved keeping a female betta with them for fry control. A betta can be a risk but a female is less of a risk. Gourami are also an excellent option and much less of a risk to the adults.  Neither will obliterate the population but will just keep it in check. I still had tons of guppies. 

I also kept cories on the bottom. That was one of my favorite tanks and I'm considering recreating that soon.
