I have bred C.aneus and C.adolfi as well as a couple others, I used a 6' wide 12" deep kiddy pool (hard plastic) conaining several sponge filters. It is not hard. A temperature drop and fresh water is usually the trigger. Here is a link www.freshaquarium.about.co/cs/catfish/p/bronzecory.htm
I did use methylene blue to prevent fungus.
