Can a goldfish throw up?
Changes in eating habits generally accompany a bout with stress. According to AquariumFish, if your goldfish is taking food into his mouth and then immediately spitting it out, he’s possibly under stress related to unfavorable water conditions.
Which animals can vomit?
Nearly every vertebrate we know of vomits. Vomiting has been observed in fish, amphibians, reptiles and birds as well as most mammals. Horses are a notable exception—as are rats, mice, rabbits and most other rodents.
