Two goldfish in a 15 gallon is already overstocked, the last thing you need is another fish. What kind of catfish is it?

As stated you are overstocked. Most people don't think that a comet and fantail are a good combination either.

What type of catfish did you add?

That is a cory, they are tropical. They prefer temps in the upper 70s to low 80s and prefer to school.

I highly suggest you upgrade the tank size if you want to stick with goldfish of any kind.
