AQUAPONICS: WHICH FISH WORKS BEST?

We believe the plant in the betta fish container will grow better. To test which fish would be better to grow red lettuce we got a guppy and a betta fish. We put them in separate containers for 1 week and then we started to put the red lettuce seeds in. To grow the plants we used an empty Activia yogurt cup and a cotton ball. It takes 2-3 days on average for the lettuce to germinate. Our results were that the plant started to grow in the guppy container for 21 days, whereas the plant in the betta fish container never grew. On the 22nd day, the plant withered and stopped growing. Due to this experiment, we were able to determine that the guppy works better for the aquaponic systems.

Conclusion
In conclusion, we found that the guppy worked better for the aquaponics system. We measured the height of the plants for 27 days. The seed in the guppy container germinated on the 5th day. The seed in the betta container never germinated throughout the project. This is how we obtained our results.
