i received a yellow fiji leather along with a trachy and a xenia a few days ago.i drip acclamated all three together for about 1 1/2 and put them in my tank.the brain and the xenia are doing great.the leather is still yellow and responds to the lights(130 w of 10k and 130 w actinic,power compacts over a 60 g)the thing is it is detaching,ripping if you will away from the rock it was mounted on.from all my research leathers dont move themselves do they?there is a little browning where it is tearing.i need advice on what to do.thanks guys.
