Gerald Bassleer shows how to identify and treat velvet disease in Betta fish. The parasite creates a gray dusty coating and can take 7 to 40 days to complete its life cycle depending on temperature. Treatment combines copper sulfate medication, salt at 3 grams per liter, daily substrate cleaning, and antibiotics for secondary infections.

Fish disease case 8 Odinium or velvet disease which is a common problem with Betta.
Oodinium.
It's a freshwater fish called in scientific.
Name Piscinodinium which is usually difficult to.
See as you see here.
On this female Betta you see a gray area, fine, dusty, but difficult to notice. Also here Oodinium on this male Betta there's a fine powdery spray on the fish.
Here you see it on a male.
Betta which is getting skinny. You see his behavior is getting.
More wasting away.
He, he doesn't look so healthy anymore.
And this is a symptom that slowly evolves.
So Oodinium you can see on some.
Other kind of observations I made here.
On a Titea cherry bar you see.
The fine dusty peppered spray coating, more.
Easy to see on this fish.
And here on this gourami you can.
See also the finy dusty spots here.
This area which is also Oodinium.
When you use a microscope you can.
Easily identify the parasites here by skin scraping. At 100 magnification you see all the many different black parasites which are not.
Moving, they are not multi, they're just.
Sitting like here in the gills.
You can see here many of the.
Black colored parasites having an impact on the health of the gills causing problems.
To gas exchange and also causing a damage causing secondary bacterial infection. So the Odinian parasites they attach fixed into the gills, into the cells and can cause lesions. The cycle of oodinium takes usually 7 to 14 days to develop. They drop off the fish, they multiply.
They call dinosaurs which reinfect the fish.
This whole Cycle can take seven to 40 days depending on the temperature. The higher the temperature, the faster the cycle will be. So the treatment of Odinium treatment as soon as possible. So if you have a treatment action.
Going on at the beginning stage, you.
Will have more success.
Raise the temperature with a few degrees so you speed up the life cycle.
And it will be easier to kill.
The baby parasites because the baby killer, you can kill the baby parasites with the medication and use a medication that basically consists of copper sulfate and also add salt, 3 grams per liter and treat 7 to 14 days.
Then you will have more success. Try to siphon off the bottom two.
Times a day so you can remove the parasites. If secondary bacterial infection appears, try to.
Treat accordingly with an antibacterial product.
Try to feed your fish with pro.
And prebiotics to help the defense system of the fish. And of course important avoid the spreading. Work biosecurity so you don't defect fish in other tanks.
