Salmon Fry week #3
The quality of the water is clear today, we changed out some of the water today. The temperature of the water is 50 degrees and the pH level of the water is 7.3, which it means that it’s getting to a more normal range on the pH scale. My teacher Eric and I noticed that some of the salmon are a light algae green color with light gray stripes and some of the other salmon are still that dark forest green color with dark black stripes. We deiced that the light algae green color salmon are developing more than the dark forest green color salmon. The light algae color fish are a lot fatter than the dark forest color fish, the dark forest ones are a lot thinner too. They are still eating off the surface of the tank. The current size of the fish food is the size of pop-rocks. Some of the salmon started to swim sideways or upside down again. The Siamese twins are still living, but they swim on the bottom of the tank most of the time. There are still about 150 salmon living in the tank.
