Hi I've read through just about every post and could not fine a similiar situation to mine so .....I bought a pair of cinnamons...I would say identical in size which is maybe 1 1/2"...I can tell them apart because one had less black on the pectoral fins. I'll call this one #1. After a few days I did see #2 submit to #1. #1 decided to host in the xenia and wouldn't let #2 share the xenia so #2 slept in the feather duster. Now 2 weeks go by and there is a role reversal. #2 has now claimed the xenia AND the ricordia and #1's tail is shredded a little. That happened in like 24hrs. #1 is definitely petrified of #2 and the submissive behavior is much more extreme than what I saw when I first got them. Is role reversal common in what I assume is 2 juveniles? Will the tail fin get better?
