Salmon fry
Does the water look murky or clear? Well, the water is really clear. The temperature of the tank is about 50 degrees. The ph Level of the water is at 7.6, which is really good. The physical features of the salmon are that they are very big and colorful. The salmon are eating really well;  the majority of the salmon eat from the surface, sub-surface, and the bottom. The average size of the salmon is a about an inch and a half. There are about 85 to 90 salmon left in the tank. The special features I have seen are the Siamese twins, they are still alive which is great and really surprising.

MY Opinion on the Salmon Fry in the Classroom 
My opinion on the Salmon Fry, well I love learning new things and so I took this class and it is fun and I have learned a lot about the salmon. When I started this class I thought it was going to be boring, but I got into it and now I love it and I don’t want to stop learning about salmon. This class is such an adventure so much to explore and learn. Well, we have had the fish for about five months now and we had them since they were eggs and now they are fish, which is sweet watching them get bigger.  Feeding them is the best because they are so jumpy and happy for the food. We started off with about 300 fish and now we have about 100 fish and they are doing well. We have the first Siamese fish that have survived after being hatched. The temperature of the fish tank is always at 49 or 50 degrees because the salmon are fresh water fish and they are cold blooded.  We clean the fish tank about once or twice a week. The tank has to be clean or the fish will die off. We do PH levels, which are the measurements of the acidic level or basic quality of water. PH scales ranges from a value of 0 (very acidic) to 14 (very basic), with 7 being neutral. Our tank is at a PH level of 7.4 which is really good.

Salmon Fry Week #4
The water is slightly murky. The temperature of the water is 49 degrees and the pH level is 7.3, which is getting closer to a normal range. Most of the salmon are that light algae green color with light gray stripes, but there are still a few with the dark forest green color with black stripes. They are eating off the surface of the tank. We have changed the size of the fish food; it is about the size of pellets now. There are about 140 salmon in the tank; we lost a few when we changed the water last week. Most of the fish are swimming normal, but there are still a few swimming sideways. The Siamese twins are still living, but we have not been able to find them.  So we think they are hiding on the bottom of the tank.

Salmon Fry in the Classroom

The quality of the water is slightly murky. The temperature of the water is 49 degrees and the PH level is 7.6, which is great on the PH scale. The physical features of the salmon; they are still a dark forest green color on the top, and a bright silver color on the bottom with black stripes. All of the salmon are eating off the surface which is great because that means they are learning that they can’t just wait for the food to fall to the bottom of the tank. The current size of the food is a little bigger than coffee grains. There are about 125 salmon fish left in the tank. The salmon are swimming fast and normal and the twin salmon are still alive.
