Need help what to do

[keda]

Hi everyone,
I have a 12 gal with 6 fishes a rock and 3 artificial plant. I am going to be setting up a 44 gallon tank soon. I'm thinking about guppies. I want allot of fish and a wide variety. I mostly want small fishes. So, I'm asking which fish should I put in my tank? I'm looking for a variety of beautiful fish that will be fun to have and are easy to care for. I also want to add vegetation and bottom feeders/ scavengers, maybe some snails.
Can you help on what and what not to put.
I also don't know fishes or what they look like.
Help :!: :!: :?

These fishes can go well with guppies and they are small.

Corydora (some type of catfish)
Neon tetra

Well that's all I have (some time ago) with the guppies.

What aboute blue neoen (are that the english name.) they are like the a little bit bigger cousins of the neon tetra, and they are more blue, they are easy to keep and fun to watch, quite inteligent to in my experience for so smal fish.
