Minnows: Survival of the Fittest

Conclusions:

My Hypothesis Was Incorrect.

The minnows in Rain Water (pH=6.6) grew a bit faster than those in Pond Water (pH=7.4) and those in Tap Water (pH=7.6).

Note: At the beginning of the experiment, I used Lake Water which I had to switch to Rain Water because the pH Level of Lake and Pond Water was the same (pH=7.6).
