Gerbil Owners?

[Lexi_Lover]

I know I have been pestering you all about how many pets I am hoping to be getting, but this one I am serious about! LOL! Ok so here it goes! I have been doing LOTS of research lately and I am hoping to get a gerbil soon and I have a couple of questions for the owners out there!

1. Can a gerbil live in a fish-tank, with clear glass and no hood?

2. How often do you need to clean their tanks/cages?

3. Can they live alone or do they need a pal, which is better?

4. How long do they live for generally?

5. I heard of "wet-tail" and my friends gerbil died of it, what EXACTLY happens when this occurs?

Thanks to anybody and everybody who helps me out!

Here is the site I went to for info, it helped me A LOT!
