Bummed out my ocell passed away.. 
I can't figure out what cause it to pass away. My water parameter is good ,temp is at 86-88 F and eating normally with the rest. What I noticed yesterday he was heavily breathing more then the rest and hiding, seems stressed. He looked healthy.
Out of the 3 one out grew the other 2 and started picking on them. Could that be the cause of his death?
