Koi & Goldfish Parasitic Disorders

Symptoms

A). Fish gasp for air at the top of the water. They sometimes flash, or jump. They rub on rocks or other objects. Gills may be bleeding.

Gill Flukes (Dactylogyrus)

Treat with: De-Los and use Koi Fix® if the fish develop any secondary infections after the flukes are gone

B). The fish have small pimples on the skin, or reddened areas with a white thread-like worm sticking out.

Anchor Worm (Lernaea)

C). Small, round, clear to whitish objects are stuck all over the fish. The fish flash and scratch

E). The fish have small clear/white worm-like objects stuck to their skin

Skin Flukes (Gyrodactylidiasis)

F). My fish are breathing heavily, have a heavy slime coat, and appear to have round, flat parasites on them

Your fish is affected by Trichodina

Treat the fish with Forma-Green

G). My fish have swollen bellies, even though they have not been fed for a couple of days. They seem to eat normally, or are very hungry.

Three items can cause this:

a). Mitospora (acites, severe bloating, pineconed scales)

c). Tapeworm
