Bent Ranchu

This is a tough one for me. :wacko:

I have a 40 gallon tall tank where my Ranchu lived all by himself. Alone, but happy.

I was away for a couple of months and had someone take care of things, including the fish. When I returned, the tank had been obviously been let go and then cleaned for my return. I say obviously because the glass showed signs of heavy algae int the corners where the scrubbing wand missed.

The fish seemed fine, so I did a 50% water change and resumed my daily 10% change.

I'm preparing a space to set up a 55 gallon tank, so decided to add a few more fish in the way of 2 small Orandas and a few zebra danios. I neglected to use a quarantine tank. A few days later, ICH appeared.

I read of a process to get rid of ICH which is as follows: over a 48 hour period I raised the temperature in the tank to 84F. I  added salt gradually over the same period until the ratio was 1 teaspoon per gallon. Performing regular daily water changes, hold the tank and salt ratio for at least 7 days after the ICH has disappeared.

By the second day of treatment my Ranchu started swimming funny and eventually began to corkscrew through the water. His body appeard bent in half. He is eating, but only swam in spurts.

I moved him to a 10 gallon tank with water from the 40. I am changing 2 gallons a day without adding salt and without heat. He slowly improved and by the 5th or 6th day he seemed just about normal, but yesterday sufffered a bad relapse, seen in the picture.

Researching the net has turned up descriptions of similar symptoms that people attribute to excessive nitrites in the water.

What should I do now to help my friend?

Miroku, That bent shape usually indicates that the fish will pass away soon. I'm so sorry about this.

As for your other tank, do fill out the form for that so we can advise you there. We are use to seeing and analyzing the data on the form, so please fill in as much as possible.

I agree with Lisa.  Most likely there isn't much you can do for the pictured ranchu.  I'm sorry.


Are the other fish still in salt?  And is the salt still at the concentration of 1 tsp per gallon in the 40?  For ich, it should be 3 tsp per gallon.  :D

This is also a symptom of Fish Tuberculosis. We would need more info to even consider going torwards that diagnosis.

The other possibilities are prolonged spasms, exposure to chemicals, physical injury, parasitic disease, Whirling Disease, but this is also a sign that the fish is on its way out. In any of these cases, the plausible option when the fish is at this stage is to humanely euthanise the fish.

I'm sorry for your situation. :(

Again, thank you all for your advice and kind replies.

I'm sorry to say that yesterday his condition worsened. Right along, he would occaisionally swim right and seem fine, then relapse into bent repose at the bottom of the tank. I had hoped he would recover and did all I could, changing water daily and feeding him. Yesterday he stopped eating and was twirling aimlessly in the tank, with long periods of laying still. He actually looked distressed, which told me he was heading down hill. I didn't want him to suffer.

I used the euthanizing method as outlined by Rachel Taylor. He passed quickly and quietly.


I have learned from this.
