Hello everyone. i would like to introduce myself, i am Alex "alx" my girl and i just got a new Betta his name is Zep ( fish in Spanish spelled backwards

)
we have lots of questions because we are new new newbies and we want our Betta to be happy so this is going to be a long post. :D
here is the story/background
before we bought him i was online for 4 hours everyday looking for betta info for about a week. the best info i found was at:
1. bettatalk.com
2. aquariumlife.net
3. flippersandfins.net
4. yahoo answers, (

5.
http://nippyfish.blogspot.com
6. youtube.com (
http://www.youtube.com/watch?v=rnxhL...eature=related)
this is my first question..
are these proper/reputable links with correct information?
(except yahoo and YouTube.. since i know its hit or miss)
continuing with the story.....after doing some research we decided to buy zep....
We live in Miami ( warm weather) and bought him at a local pet supermarket store. that same day we also bought a marina aquarium starter kit zen 1/2 gallon, with the light.
from the store we also bought betta water, and hikari Betta bio gold food.
the people at the store told us to feed him 4 pellets every day...
after setting Zep up in his new placewe realized that the aquarium was definitely too small, ( it does look pretty so now we use it a night lamp bamboo aquarium... no fish)
is this called a planted aquarium?
given that we realized that it was too small we went on to look for a bigger aquarium... after reading lots of blogs and rants from people online about tank sizes i decided that we should get a 2.5 gallon tank.. ( we can't have something bigger right now... maybe sometime in the future once we know more about fish/tanks/plants)
so getting back to the story... over the next week we bought zep a 2.5 gal aquarium ( glass)
we got a lid and some rubber bumpers to space the lid a little and give some room for air.
we also got some black rocks... for the base.... dunno the name .. compound i think....
3 aquarium rocks
3 plants. (i think one of the them is called argentinian sword or blade.. something like that... not sure on the names of the others)
we also got 2 led lights, but i put tape on them becuase they were too intense that diffused them a little.
as of now they are dimmed down even more because i put vellum paper behind the aquarium and the lights a further back. ( i'll post a pic soon)
we also got a termometer
spring water
ph thingy to check for ph
and amonia thingy to check for amonia.
and conditioner to condition the water.
here are some pics of the setup as of now ( without the vellum paper)
Zep has been 1 week in the new tank. he seems happy becuase he blows bubble nest and swims with excitement....
we are changing his water every 7th day
is this too little?
sooo. now what i am noticing is that there is kind of like a clear greasy film
cover on the top of the water.. ( we don't have filtration or aereation)
i don't know if this is a bad thing or not (i can't find concrete info about this).
so here are my questions for where i am stumped right now.
is the greasy film cover on the top of the water a bad thing
( i break it up every day to allow for the oxigen and co2 mix that happens on the water surface)
if it is bad... should i get an air pump? or a filter? or both?
if i need to get one or the other or both... is there a way i can hide them so its not in direct sight?
are there any good ideas or brands to maintain good water quality for Zep and the plants.
thnk you for reading such a long post.. and i apologize for making it too long.
i just though that i would give you the run down of our first betta experience :P
Thanks again for any answers/comments/ suggestions.
we really do appreciate it.
All the best
