Fish Choices

Question
Hello. I have a 28g tank and I need some help on what freshwater fish I should put in it. I have an 18g tank also and it's full of guppies, platies, and a Chinese Algae Eater, which has grown really big. I went on Yahoo! and asked this question, so far I got:
*6 Lemon Tetras
-6 Glowlight Tetras
-4 Bronze Cory Cats

This suggestion:
*Move some of my guppies and platies to the tank
-4 dwarf gouramis
-2 Cory Cats

And lastly:
* 2 tinfoil barbs
-1 Redtail Shark
-1 Black Shark
-5 Tiger Barbs

I have had 3 years experience with just guppies and platies so I want to try something new. Any suggestions?

Answer
Erika,
Since you have exp. already with guppies and platies, why not give some Sailfin Mollies a whirl?
All you need to do is ad some salt to the water as they like that.
You can get some great looking fish and you will have babies that you can trade back to the shop for other items.
There are lots of varieties to choose from.
If you need more info on them, just ask.
