So I have been having issues with my montiporas as of late. They experience death and I have no idea why. Parameters are in check and I have actually posted bout it. The death will come over night and then go on for a few days and then stop. Well doing some research we have concluded it is most likely monti eating nudis. I guess the reason I have not seen these issues before was that I had wrasses in my tank but I started taking sand out so I removed them. Looks like im going to have to put a 6line wrasse in to help bandage this problem ughh. Well at least its not the worst issue to have but certainly is not the best scenario. Nice thing-is I will be home for a week so I will be able to get me a fish and make sure he is good to go to put into he display. I did have a 6line before and he was fine I don't really remember why I got rid of him lol but I guess he will be coming back but one question is will he pick at a 4-5in copperband butterfly who has been established?
