I have a tank with many Amanos that will regularly swim up the the surface to grab some food during feeding time (as if they're too impatient to wait for their own food, which they get more than enough of). This has been a regular occurance for some time with no issue. Suddenly tonight I am seeing that they are often swimming up, then falling while upside down. They would typically hit the floor, and then get back up as if nothing happened. As I'm writing this I have noticed one begin to do it, but it is not longer moving when it hits the substrate... it is worth noting that I recently added some new driftwood (about four days ago), but I did boil it for approximately an hour beforehand. Any suggestions for how to diagnose this issue?
