This has nothing to do with bettas...but :/

My Adolf (oranda goldfish) is sick i think...he usually swims around all day but for the last two days hes sitting at the bottom of his tank with his fins all clamped up. I'm not sure what to do for him.
But I figured all fishy friends are welcome on this forum and I just wanted to share an update...a kinda sad one...but...I hope he makes it.

I'm so sorry about your goldfish! If you need any questions answered about goldfish, I recommend you pm Lupin. He knows EVERYTHING about goldfish. He even did surgery on one.

Hi,

Has your oranda been treated with praziquantel before? Your goldfish is exhibiting typical fluke symptoms. Flukes are dangerous parasites categorized as trematodes that attack the skin and gills of your fish. Their presence can be associated by clamed fins, bottomsitting, flicking and labored breathings. Treat ALL your fish in contact with the oranda with prazi. Should be available as Droncit or Prazipro and dose at 2.5 mg per liter. Ignore the instructions prescribed on Prazipro bottles. It takes 3 days before prazi wears off so redosing is necessary.

Dosing schedule
Day 1 -- remove carbon, perform water change with vacuuming, and add Prazi to tank
Day 2 -- add Prazi
Day 3 -- do nothing
Day 4 -- do nothing
Day 5 -- do nothing
Day 6 -- add Prazi
Day 7 -- add Prazi
Day 8 -- normal partial water change with vacuuming
Day 14 - normal partial water change, then add prazi
Day 21 - normal partial water change, then add prazi
Day 28 - normal partial water change, then add prazi
Day 35 - normal partial water change, add carbon, treatment is complete

Remove carbon by the way.
