Gerbils!!!

So, I just adopted a gerbil 3 days ago, I named her Penelope.
Yesterday I went back to get 'ma' and 'sis'. I got home and 'ma' turned out to be DAD! 0_0
I called the petstore, turns out all the gerbils were male. So Penelope is actually Phillip (but Phillip didn't look like a Phillip...)
So daddy's name is Tibalt.
Penelope became Romeo
and the last son became Thor (greek god of thunder)
They are so adorable and fun to watch and play with! I have never had a gerbil before, I have had 3 dwarf hamsters and a guinea pig

Any advice on them would be helpful ^^
They are all friendly and let me hold them and play with them and don't bite.
Although they killed their wood and straw house in a matter of 3 hours 0_0 haha.

I'll be adding pictures of them soon

***Please note, I'm not a huge Romeo and Juliet fan, but I loved those 2 names***
