Abstract
Purpose :Koi fish (Cyprinus carpio) are a prevalent type of ornamental fish worldwide, including in Iran. The purpose of this abstract is to investigate the cause of imbalance in an aquarium fish.

Method : A koi fish showing signs of swimming imbalance, unable to swim and generally staying at the bottom of the aquarium, was transferred from Karaj to a veterinary hospital in Tehran.
No parasite infection was detected upon the initial examination of the fish's skin and gills. Throughout fish history, there has been a documented instance of a significant temperature-environmental disturbance. Next, the fish's swimming bladder was prepared for radiography and ultrasound imaging for additional examination.

Results: Lateral and dorsoventral radiography revealed that the posterior swim bladder of the fish in question was smaller than average. No motion or alteration in the contrast level of the swim bag was observed. The ultrasound indicated that the internal organs were normal. A gadget was created to assist fish in swimming by allowing them to float using a plastic belt and unolith. To prevent secondary bacterial illnesses, administer Enrofloxacin at a dose of 3 cc per 100 grams of food for seven days.

Conclusions: Complications associated with the swim bladder are frequent in fish like koi and goldfish, typically stemming from environmental stressors or genetic issues.
