He will make another if he wants to but you have to do the water change when it is time to do it so if it has to be disturbed he will appreciate the clean water more than you know. Just change about half of the water, please don't do 100% changes as they are hard on them. He likes you and will understand if his nest is disturbed. If he wants one he will make another one, if he doesn't then he will wait a while. It will be okay I promise. He is just giving it to you as a present so go ahead and give him some clean water he will like it. It is okay.
