Gill flukes or parasites
Swim bladder disease
High ammonia levels or poor water quality
Insufficient oxygen levels

When considering these potential issues, it’s important to examine each factor closely.

Overexertion During Spawning or Fighting:
Overexertion during spawning or fighting occurs when a betta fish expends excessive energy in mating displays or aggression. This can cause the gills to protrude as the fish struggles for breath. The American Veterinary Medical Association notes that bettas are territorial and may exhibit aggressive behavior, which can lead to this condition.
Gill Flukes or Parasites:
Gill flukes or parasites are external organisms that attach to the gills and interfere with proper respiratory function. According to a study by W. L. Wong (2007), these parasites can cause inflammation and swelling, leading to visible gill protrusion. Treatment often involves specific antiparasitic medications.
Swim Bladder Disease:
Swim bladder disease refers to a condition affecting a fish’s buoyancy and can manifest with gill swelling as the fish struggles to maintain its position in the water column. Symptoms can vary; studies show that swim bladder issues are common in bettas due to overfeeding or genetic factors (M. J. V. Lemoine, 2015).
High Ammonia Levels or Poor Water Quality:
High ammonia levels or poor water quality is a significant concern in aquariums. Ammonia is toxic and can cause respiratory distress in fish. The World Health Organization recommends maintaining ammonia levels below 0.5 mg/L in aquaculture settings. Testing and proper filtration can prevent this issue.
