Hi Buggy,
Take a look at my Breeding Barbatus article listed in 'The Hatchery".
http://www.fishforums.com/forum/hatc...-barbatus.html It has a lot of pictures, as well as a short video clip, showing everything you need to know. I use a bare bottom 20H, with a spawning mop for breeding pandas. The spawning mop provides a place to lay eggs, as well as giving the female a place to rest, from overaggressive males. I watched a male chase a female carrying eggs around...for over 5 minutes (trying to spawn). Since then I've used the hanging type spawning mops. Also; the absolute best conditioning food for cories is live black worms. You'll see the Barbatus eating black worms at the beginning of the video.
Hope this helps! Good luck!
