Just an update, it was Oct 14 when this piece showed exposed skeleton. It is now Oct 18 and it currently shows no exposed skeleton. The only change was: moved to bottom of tank on sand bed (low light) and perhaps less water flow (but not significant change). I did not yet try Acan+, nor did I try to force additional target feedings. Let's see if this holds up...
