PostSubject: What's wrong with my koi fish?   What's wrong with my koi fish? Icon_minitimeThu Jun 07, 2012 1:35 pm

I am a new member and new to taking care of my fish. We just purchased a home that had an existing koi pond. We have owned the place for 2 weeks now and trying to learn how to care for our pond and fish inside. We have 2 large koi around 12 to 14 inces and 5 small koi around 5 inches. I have 2 problems I am hoping I can get some advice for. I want to thank you in advance for you help.

The first problem is one of my large Koi who was the most active and eating all the food started getting fluffy white stuff growing on it. Then last night it looks like dark green or black growth has formed on its back. Almost like algae has grown on it. The fish is just sitting still at the bottom. I had a lot of algae growth in my pond when I noticed the white fluffy stuff 2 days ago. I removed half the water and gave it a good cleaning. Then refilled and conditioned the water. I bought some medicine at the local fish store and treated the water with it. I also added pond salt and a barley barrel. Then I noticed the black growth last night. I am really worried about it, as the other fish seem to know the fish is sick and protecting it. Sorry, I don't have any pics at this time. Any adive would be helpful.

My other problem is the other fish seemed very scared. Last night my neighbor came over and told me that he has seem a blue herron on the roof of our house and he showed me a picture of it. He came over and scared it away. What is my best option for protecting my fish? A friend of mine told me one of his friends had the same problem and they bought a fake bird or blue herron and placed it need the pond. Is a net the best option?

Hi Mike,

First things first, have you checked your water parameters -nitrate, nitrite, ammonia ?
Sounds like the white fluffy stuff is a fungus and the black stuff algae which is probably secondary
to parasites on your fish.
You need to scrape and identify what parasites are on your fish. If this is not possible, a broad spectrum medication like malachite green or methylene blue may help, but one really needs to find the cause of the problem first.
You mentioned you conditioned your water--how did you do this? Also, what medication did you use? it is also very dangerous to use different medications in a short space of time as this can be toxic to the fish and stress it. Hopefully you have a dealer or hobbyist to guide you in your area. The most important advice I can give you, is to identify the problem first. You also need to work out the litreage of your pond.


On your second problem, a net is the best to keep birds out.

Regards,
Costa.
