Corydoras Haraldschultzei A Month After Purchase

I recently rearranged and added a new HMF style filter to the 20Long that houses my C. HaraldSchultzei.  They were very spooky in the previous set up so figured I couldn't go wrong by rearranging. 

They are already acting more confident about feeding and being in out of the plants.  They seem to enjoy hanging out near the HMF foam toward the front.  In the video I had just placed the filter in and they were investigating the back glass.
