Conduct partial water changes of at least 25% weekly to remove harmful waste products and replenish the water with fresh, dechlorinated water.

Test and adjust water parameters:

Regularly test and adjust the water parameters to ensure they are within the appropriate range for angelfish. Aim for a pH between 6.8 and 7.8, ammonia and nitrite levels at 0 ppm, and nitrate levels below 20 ppm.

Increase water flow and aeration:

Improve water circulation and oxygenation by adding air stones, powerheads, or increasing the filter output. This helps remove waste products and promote healing.

Quarantine:

Quarantine Affected Fish If possible, move the affected angelfish to a separate quarantine tank for treatment. This prevents the spread of the infection to other fish in the main tank and allows you to focus on the affected fish’s recovery.
