Yesterday we added the zeolites into the tank, the fish was taken out when we added it to minimise the stress on the fish but when we threw the water and fish back into the tank it seemed a bit jittery and wasnt calmed down for a very long period of time. The fish kept swimming up and down and avoided going way down to the bottom of the tank where it usually would swim, it is as if it was a bit afraid of the new addition to  the tank but today it sort of started swimming back down to the boottom and made itself used to the zeolites. Its back to its usual behavior. Go Wendall :)
