Well,

Do you feel like you can take the challenge?
Can you honestly be that expert keeper that can get them all feeding?
Have you ever done something like that before???
Will you be upset if one of them goes belly up due to lack of food?

All things to consider. There is a reason why they are so cheap!!

I personally wouldn't do it... I've done it before, and it is more of a headache than it is worth.
