April 10th-Aquarium Observations

The aquarium is going well. The fish are swimming around quickly and appear to be healthy. The goldfish seems to continuously bite at the gravel and rocks at the bottom of the aquarium, which might mean that he is hungry? Also some of the tetras seem to stay together somewhat in a group and follow each other around. The filter is working well, bubbling and pouring out clean water as it is supposed to. The plants seem to be doing well as well, and are normally very still in the water. When we did the nitrate test the water had 10 ppm of nitrate and the ammonia test resulted in 0 ppm of ammonia. Both of these were in the acceptable results in order to have fish living in the water. Because the results were good and acceptable to have fish, we did not make any major changes to the aquarium because we didn't need to. Also, the temperature of the water was 20 degrees Celsius or 69 degrees Fahrenheit, which is a normal temperature.
