Yeah

I had a similar issue with my duncan, it was doing great then suddenly it started closing up too. I didn't change anything, same water flow, same lighting, same everything. I did move it to a different spot in the tank though. I'm not saying that's what's causing the issue, but it's something to ...

He was chillin' at the bottom left corner of the tank for over 6 months, doin' great, just recently moved him to the top.

I got this duncan with one head a year ago and it was doing alright, same flow, same light, nothing changed. Now it's closing up every day, like this. I'm stumped, any ideas what's going on? What can I do to help it out?
