Help Me Please!!

[krazykrystal16]

I am new at this fish thing.......... and i have a few hundred questions (hee hee). We bought a fish tank 3 weeks ago, got the levels all good and bough a few fish last week-end!
So..... this is what we 1st got- 10 neon tetras and 2 angel fish, they did so well that we went a few days later and got a silver dollar, 2 red parots and a sucker! The parots seem to be very aggressive, we have had 5 neon's go missing and the other fish seem so sad....... we have taken 1 of the parots out and placed it in a tank on its own. BUT what do u guys think should i get rid of the parots... because we LOVE the angel and neons.
I live in a very small town.... and it seems like the pet store we went to dosent know anything about it, i keep calling and asking them BUT they alwayz say they dont know or try and guess.
Im juust going to make a list of the things i would like to know hopefully someone can HELP me!
- how often do i feed and how much?
- when do i turn lights on and off?
- what is the best temp. to keep it at?
-the water is a little cloudy, but levels are all good what do i do?
-How often should i change water (and how much) ?
-should i have real plant life in the tank?
I really hope someone can help me!!! Thank-you for taking the time to read this!
