Hi, I added my fourth and final goldfish to my 55g yesterday. He seems
very happy and sooo at home. My Ryukin has behaved very oddly since
his introduction. She is just sitting in the middle of the
tank............
================
Maybe she's adjusting to a new tank mate. Suddenly there's a new fish!

I'm sure it's nothing to worry about. :-)

Wild guesses when it's obvious you didn't read the original posters
question, or at least comprehend it.
The original poster didn't say if she had put the new fish in quarantine or
not. Goldfish from petstores are notorious for bringing diseases and
parasites with them.

Fish don't sulk, any evidence of bullying? fin nipping?
