I don't think the other tank, as you point out, isn't a better option.
I don't know if it is necessary for it to have a friend...like I mentioned if it was, or may be, a male and female it might make it worse? I'm sorry I just don't know for sure.
Can you get a picture of the other fish?
Can you please post a couple of pictures of the tank he/she is in now? Also, how many Panda Cory?
Depending on the situation it might be better to keep the fish alone for now. If the unknown sexed fish is utilizing the cave and doesn't appear stressed that would be my choice.
Also, what did you observe in your tank during the time you put them in there? Any aggression? Fish freaking out?
I can give you a better opinion if I see some more pictures.
Just out of curiosity, how much did you pay for your Gudgeons?
