Common Causes of Floating at Surface in Arc Eye Hawkfish

Ammonia and nitrite levels are elevated, causing stress and difficulty in breathing.

Malnutrition

Possible

Insufficient dietary variety or poor-quality food leading to malnutrition.

Internal Bleeding

Less Common

Internal injuries can result in bleeding, making it difficult for the fish to stay underwater.

Parasites

Less Common

Parasitic infestations, such as monogenetic trematodes, can weaken the fish and lead to surface floating.

How to Diagnose

Follow these steps in order. Stop when you identify a likely cause and move to treatment.

  2. Inspect the fish for external signs of injury or parasites

    Look for any cuts, wounds, or signs of parasites like spots or white spots.

  3. Observe the fish's behavior and appetite

  4. Gather a water sample
