My wonderful male Betta Sushi has build a pretty big looking bubble nest, since he is near no females and i have no plans on putting him near any for the time being, would it "upset" him if the bubble nest was damaged when I change his tank. Sushi seems a moody type (he attacked anything I put with him) and i dont want him getting upset and refusing to eat or anything like that. so, would it tick him off if the bubble nest is damaged?
