Beta Fish Survival

The purpose of this project was to observe the survival of a beta fish in a 3 litter Ozarka water

bottle. It was hypothesized that the fish would survive if it was fed and the temperature, the

ammonia and the nitrate levels were appropriate. The null hypothesis is that a beta fish can

survive in an artificial environment. The ammonia level that was introduced into the habitat by

the food given to the fish, would kill the fish when it got to a high level. The nitrate level would

get higher for the fish excrement. The temperature could kill the fish, but this factor was not

controlled by the fish’s actions. The ammonia and nitrate levels were regulated by changing the

water. The beta fish would be placed in a different smaller recipient,
