I have had my leather for about a week now and the first day I got it opened up and now it have shrunk and have not opened up since, my parameters are good and all other lps corals are doing good
Does it look a bit waxy? Some leathers will go through shed cycles where they close up for up to several days, begin to look waxy on their surface, and then shed. Not unusual at all for a move to a different tank to trigger this.
