Hello there!  Let’s see if we can help :)

Did you quarantine the new fish before adding?  Any other fish showing symptoms? 

Can you redo your nitrate tests and make sure you shake the snot out of them? In a cycled tank there should be some nitrates showing - can you try again?

I was only able to quarantine for a few days, they were my fish store (dallas north aquarium, for those in Dallas area) for over 2 weeks when I got them.  1 new fish has spot, 1 new does not.  2 existing fish have spots,  the third does not. 


These are pics of nitrate right now.

Now a small white pin bone looking sliver is coming from a few of the bloody spots.  Thinking anchor worm? Thoughts? Thanks! 


Photo please if you can.


Those logs are the hollow? If so I would get them out. Goldfish produce more waste since they graze all day and are big fish. Orniments like that will hold water and become stagnate over time. Unless you have a bubbler in them or wash them ever few days they aren't good for them.

That would be my fist thing to do. I want to see what @Arctic Mama has to say👍

Agree we need closer photos of those spots, and the lack of quarantine time makes anchor worm a distinct possibility.  Their life’s cycle varies wildly based on temperature, but inside of a month is completely possible if the tanks aren’t running above 80 degrees.

I’d say that’s showing some trace nitrate, but it’s definitely low.  And you shook the snot out of both bottle 2 AND the tube, right?  30 second shake on the bottle and then a minute of shaking/inverting on the tube?
