Illness & Symptoms
How long have you had this fish? Approx 2 months, she was the first fish i purchased
How long ago did you first notice these symptoms? Last night

Explain your emergency situation in detail.

Exactly a month ago i posted a query on the forum as i was not sure if my female swordtail was pregnant or bloated, 3 days later i saw 1 fry which was eaten by either the endlers or the corys. The female sword must have saved some sperm and was pregnant straight away. This time she got much bigger and became even more piggy with food. Last night when i was checking on the tank i noticed she was shaking, i was soo excitied thinking i would see fry being born, however the excitement turned to worry as she was swimming and shaking, i thought if she was in labour she would be in a corner and still. I did a google search and it sounded like she was shimmying. It said the causes were stress, poor water and bloating. As she was/is pregnant i didn’t want to do a water change. In the morning when i went to feed the fish i noticed the shimmying had stopped but she was covered in white fungus but was swimming happily and ate a lot. I didn’t have a quarantine\hospital tank so i rushed to town bought a small tank heater etc. I tried to catch her in the net but she wasn’t having any of it. I had to remove the filer and ornaments before i could net her. The second she got in the hospital tank she went so still to the point i thought the chase and whatever she has had killed her. I moved the net near her and she swam away so she is still alive, just barely moving. I added melafix and primafix to the hospital tank then tested the old tank water and parameters are as above, however still changed 40%.

Can anybody advise what could have caused the sudden shimmying and subsequent body fungus

Should i be treating the whole tank

As always many thanks in advance

Columnaris, a really bad bacteria. Best to euthanize.
No need to treat the tank, but be prepared to remove any obviously infected fish.
Thank you I think, it sounds like an awful disease. I'm really sad to know she will not survive and that I may lose some of the others if they start showing symptoms. I don't think I can euthanize

Sometimes you have to put a fish out of its misery. The symptoms you see on the outside are often worse on the inside. Imagine the agony.
