My calico fantail goldfish have developed red streaks in their fins. What can cause this?

hemorrhagic septicemia. Its common in coldwater species. IT attacks the blood vessels and eventually kills the fishes heart.


Its a hard to treat disease. It starts at the fins, then the stomach gets red and red streaks form. You can try medicine for it.

Will it transfer to my koi? What can I try to give them?

I had that a long time ago. Maracyn-Two worked pretty darn well, though I would only recommend such a harsh medication for severe cases. Otherwise, Melafix + Pimafix.

Could this have been caused by my koi dominating the tank and making the goldfish hide in the corner? They have been stressed for about a week.

Hmmm, how big is your tank?

its caused by poor water conditions

drumachine...it is about 25 gallons. I have been working on getting the koi out into their own tank or pond now that the snow has melted. they are about 3" long now. The fantails are actually bigger, but have been bullied by the koi lately. I have always done water changes, but I guess I will need to increase the amount I change.

75% would be ideal. Goldfish/koi are notoriously dirty fish.

I like to call them "little oscars". They certainly compare to oscars pound-for-pound in waste production.

In the aquarium, being dirty is a problem. But when I get them into a pond...the dirtier the better(great fertilizer for the garden).

make sure you treat that fish soon. I had a aulonocara sp. albino cichlid get the disease, and he slowly wasted away, and got the secondary popeye from it. Eventually, he wouldnt eat and you could tell his heart was giving so i had to euthuanise him

Strangely enough, I did a couple major water changes and the calico with the worst red on its fins and tail is clearing up.

All is well in my tank, no meds needed. The water changes are the key.
