Introducing a newer gerbil to my new(ish) gerbil
4 days ago I bought a new gerbil, however, upon getting home I realized that I really should have bought her a friend (since they thrive in pairs). Without money to afford another gerbil and a attachment to her gerbilarium (where its plastic tank on the bottom and cage wiring on top), Shantotto (my gerbil), had to bear with my fiance and I as company.
So, 4 days have passed, and now almost 5. Shantotto is comfortable with both me and my fiance that she no longer is startled when I put my hand in cage to check her food and water, and will even take treats from me. However, I don't want Shantotto to be lonely. I can only imagine human company can only do so much...she probably would have a much more fulfilling life with us if she had another gerbil to play with when my and me and fiance are not around. Yet I have a nagging little fear that if I buy her a playmate, hand taming will become twice as hard (my fiance bought budgies in a pair once...we've owned them for years and no matter how hard he tries, they prefer their own company to his).
So, my first question is this: Is it difficult to hand-tame two gerbils at once? If not, would you consider it hard for a first-time gerbil owner?
I've also done my research and I've discovered the split-tank method of introducing new gerbils to one another. Since I have a gerbilarium, I could imagine it would be a little difficult to split in half, especially since the water-bottle is on one side and the food dish on another. However I was thinking that since the current cage I have at the moment might be a little too small for two gerbils, that if I bought an attachment for it, would it be the same concept of the split-tank method if I put the new gerbil in the new cage/gerbilarium/whatever and set them right next to each other?
If anyone could give their advice, to a first-time gerbil owner who just wants to make her gerbil the happiest she could be, I'd really appreciate it! ^-^
