If you have a bronze cory with albino cories, they are both species c. Aenus and they should shoal together so it shouldn't be lonely.
Personally, I'm the least aesthetically attached to my bronze cories as well and would rather increase the numbers of the others, don't feel bad! Everyone has personal preferences with species.
As others have mentioned, some LFS
will take them, some won't. For me, only one of mine will take fish for adoptions because they have a separate tank, but theirs currently has an enormous oscar and a CAE
so I won't bring fish to them.
Another option is craigslist or local pets groups on Facebook. I found two people who I traded fish with which ended up being awesome. My fish got happier homes and I got some cool stuff out of the deal.
I also rehomed a huge catfish to a local pet store that had a 500 and 3500 gallon pond. I felt guilty, but once you realize the fish is in a better environment, the guilt goes away
Just a note: cories do best in groups of six or larger of the same species. The more the better IMO
. You can have single types but they won't show all of their beautiful behavior and stress more easily.
