I have a new Betta that I just brought home last night. I added dechlorinator to the water along with a bacterial supplement. Unfortunately, he won't eat. He does see the food, sometimes swims toward it, but doesn't try to eat it. I was told by the store that this can happen due to stress for a couple days, I just wanted to get some more opinions from people that I'm sure are more familiar than the store clerks with Betta behavior.
Also, if this goes on for more than 2 days, what can I do for him?
