Okay, actually I intend to write up on this subject but I didn't get to do it. So since you asked ..... here goes

I call the lesion on the head Wen Rot. Wen Rot or some people call it HITH ( Hole In The Head) disease from what I know, is mainly caused by bad water condition. Many web sites link HITH with Hexamita/Octomitus but I don't think it usually true in our case, the best way to know if your lesion has any relation to Hexamita/Octomitus is a very soft ( use your hand to touch ) stomach or a colapse one. I would estimate that 80% of Wen Rot in our case is caused by something else, as they fish usually does not usually display the normal symptom of Hexamita/Octomitus ( lethargic, lack of appetite and colapse stomach )

The cure of wen rot is really very simple actually. Keep water condition perfect. Change 50~80% of the hospitial tank every other day. (Note that your hospitial tank should be relatively sized, in relation to your fish. eg a 3" body only goldfish, should at least stay in a 1 foot plus guppy tank filled to 90% full with a air stone.) I use Interpet 9 ( Anti-Internal Bacterial ) but I guess you could use any good Anti Bacterial medication. I dose 1.5 times recommended dosage (explain this other time) and add 0.2~0.3% of salt. If the lesion is small, the treatment will take a week or more before the wound disappear. If the lesion is big, it take longer to stop it's deterioation and a longer time for the wen to recover usually partially ( my took 1 month pulse ), if the wound is really big ( I have not experience it personnally ) the wen will not close back and it will leave an ugly scar on the wen even when the disease is cured.

Trying to cure wen rot is tidious because of the need to keep very good water parameter. A slip up in the water change procedure and the wound will turn bad again. And things will head south very fast.

The main cause of wen rot is bad water parameter especially high nitrate and/or Ammonia. There are others that might contribute to HITH ( usually related to cichlids ) but could be one of the contributing factor in goldfish too. They are

1. Hexamita
2. Calcium Deficiency
3. Vitamin C Deficiency
4. Activated Carbon
5. Stress

P.S. I have successfully cure wen rot. But I have never successfully cure any goldfish with suspected Hexamita. Metronidazole is recommended against Hexamita but I am not aware of where to get it other then the vet. And the only fish vet I know in Singapore other than those in the AVA is along Jalan Kayu.

Hmm,Thanks alot!huhMy poor goldfish!

May I know how much interpet 9 cost?

I been trying to feed them with forzen blood worm with Vitamin c recently and I think Blood worm got alot of calcium right?

I kinda of scare of sick fish.alway die in my hand.after water change at nite..........just my what happen to my poor Neon tretra.

Blood worm especially the frozen ones are all water. If you want Vit C. drop a slice of peeled orange in

Neon Tetra is always getting the NTD one, very hard to cure one. If one of them gets it usually the whole school will be wipe out in time.

Your best bet would be to change water more often. Can you tell us what the number of goldfishes ( or any other fishes ) in your tank, size of goldfishes, and the size of your tank. Also how often you feed and how often you change water ( by how much each time ). Then maybe I can get a better picture to help.

I got three gold fishes(two 3 nich,one inch),9 tetras( different species) Still guessing what fish they are...cos not I buy one.........then I got like 30plus guppies plus 30 over fries I lose count too many....huh and two cat fish small one......

I change water once a week its alway green alway particles flowing around and my power head in the water with pounge( sorry cannot spell correctly) but its alway got choked easily with dirt until the motor come to stop often.
Then input with one airpump with only one air supply recently.

I been tring very hard trying the control the water condition but alot of particle cannot be filter due to the pounge I using........but I cannot chnage this as the small fish will sucked and killed.....that really sad to see.

I change water at like 10pm......or evening time if can I change at 8 am if I got time before I go work but every time I aged the water or add anti-chlorine.

Three feet tank only


I feed them alot like 5 to six time......I think I alway over feed........4 cube of blood worms and fish foods.........they really eat until stomach so big.lucky never die:P

But sometime water change fish die.........maybe i just pour the whole bucket right in at one go.....If fish sick 50 % WC or more.

Anything wrongs Thanks

Well you all are so helpful...thanks you.
I loves ranchu.!!!tmy fav one is sick........... smaller one now got red spot on scale too........really headache!!!!

1. Your tank is over crowded. Thats about 70 fishes in your tank it will get less as your goldfish slowly eat your frys but it still too much.

2. Your pump is not working well, which means that your filter is probably not established with BB. The result is that your tank has high Ammonia level.

3. 5 to 6 times feeding a day of 4 cubes and fish food, flakes I assume since you keep guppies, that gonna increase your Ammonia load pretty fast.

4. You change water once a week and you said when fish sick you change 50% or more. So I assume when fish is not sick you change 40% or less. Thats proabably not enough to remove your Ammonia.

What you should do is firstly get an Ammonia kit to test your water.

Next try to get another 2 feet tank for your 3 goldfishes, the goldfishes will thank you and your guppies will thank you especially the frys

Meanwhile take a pail or spare tank ( hospital tank ) to keep the ranchu and treat them for the lesion. I would advise you to change water for the pail or hospital tank ( should be big enough to comfortably keep the 3 ranchu in it ) at least 80~100% every other day, add 0.3% salt ( thats 3g per 1000ml ) and Interpet 9 as recommended.

That should solve your immediate lesion problem.

you have too many fish lah...

Thanks for everyone help here!Wow people are helping here but one last question why medication is needed at 1.5times and thanks.

You know, when my child ( when very young ) is sick, the doctors give medication according to the weight of the baby or child.

Interpet or most medication for that matter is targetted at the general fishes. That means 10ml per 100 liters is suitable for a 5 gram tetra or a 1Kg koi. To me that doesn't sound correct and there was a discussion long time ago here on this subject. From then onward I made the decision to dose my goldfish around 1.5 time the recommended dosage. Thats just my personal opinion, I have no scientific statistics to back it up. But so far it does work for me. Therefore I sometimes advise likewise when the situation is bad, but the owner have to understand my stand and make a call for himself.
