Goby in QT tank

[Poisonus Yeti]

I have a yellow watchman goby currently in a QT tank and my question is this:

How long should I keep this goby in QT if no disease/infections are visible? I've read that these little guys are pretty resistant to diseases.

Also, this is my first fish so there are no other fish in the DT.

Thanks for your help!

ideally 60 days.

Disease resistance verses immunity are very different. It's always better to be safe than sorry, and though he doesn't show any signs at all, it could be in his gills, or places not visible. Most COMPLETE qt lasts 6-8 weeks.

Ok, so I've noticed two pink spots on this little guy. They are probably 0.5mm in diameter. One is located on his body, just below the rear dorsal fin. The other is located on his side right where the caudal fin begins.

He might be "flashing" a little bit (turning his body and trying to scrape the glass bottom) but I'm not sure about this one he could just be acting a little odd.

I've also seen him move towards the top of the tank kind of clinging on to the silicon near the top of the water.

My first guess would be a parasite of some form that is currently too small to see that is also housing itself in this little guys gills. I'd really like to get a more definitive symtom before I start treating.

Please help diagnose these current symptoms. I wish I could get a picture but my digital camera cannot get in that close!
