Common Questions About Koi Health

How do I know if my koi is sick?
Watch for changes in behaviour such as lethargy, flashing (rubbing against surfaces), clamped fins, loss of appetite, or visible marks on the skin. If you notice any of these signs, contact a koi health specialist for an on-site assessment.
Do you service areas outside Gauteng?
Our primary service area covers Gauteng, including Johannesburg, Pretoria, and surrounding suburbs. For enquiries outside this area, please get in touch and we will do our best to assist.
What does an on-site consultation involve?
We test your water parameters, perform a microscopic scraping of your koi’s skin and gills, identify any pathogens, and provide a treatment plan tailored to your pond and fish.
How much does a consultation cost?
Every pond is different. Contact us for a free initial discussion and we will provide a quote based on your situation.
