Books have been written on the question you ask. I'd recommend checking out
online info such as the following page
http://www.thekrib.com/Plants/ It has info for many different levels of
aquarists and will get you started off on the right foot.

It's a great hobby, but I warn you, there's a lot of info to assimilate at
first. Don't let it stop you though!

Ok, I have an established 45 gallon fish tank (10+ years). I have
artificial plants and would like to replace them with real ones.

So here are my 'dumb' questions:

What plants should I start with?

How many plants should I put in the tank?

Will my plecos eat certain plants?

Any other help would be appreciated

Thanks
Brent
