Day 5 - Clear water.

Wednesday Nov. 9, 2011


The water in the fish tank is now clear and both zebras look good.   I think that the fact that I reduce the air flow on the filters works well.   When I took the picture, I notice that we have connections with math.


1. Where do you observe examples of refraction? (I found at least 2)
2. Where is one example of reflection? 
3. What other math questions can you create based on this picture?

Day 4 - Zebras on the tank

Tuesday Nov. 8, 2011

I put the liquid to reduce the ammonia and released my two zebras.   After 4 hours on the tank they look healthy.    Also they look small for the tank.  The girls at the fish store told me to wait until I see that this zebras survive before I add more fish to the tank.



Sometimes this zebras are difficult to see.  

Could you find them on this picture?






 

Here they are! 
It's a good adptation, don't you think so?

Day 3 - A big disaster!

As soon as I entered in the room, I ran to see the fish tank.  Guess what? Both mollies were dead.  At the end of the day, I took a sample of the water in the tank and I went to the fish store to test it.  They told me that you do not have to use pure fresh water when you set up your tank.  Fish need not only water but also minerals.  It’s s better to use spring water or tap water with water treatment.  

I bought two Zebra fish because they are sturdier than the mollies.   Also they gave me 2 milliliters of liquid to reduce the ammonia (contamination) in the water.  

Day 0 - Set UP

Friday Nov. 4, 2011

I set up my 10 gallon fish tank with gravel, under gravel filter system, a thermometer and a lamp.  I went to the Fish store and bought pure fresh water, a big 3 lb limestone rock, and two white mollies. The fish tank looks amazing!



I selected limestone in order to resemble a natural habitat.
