Ok I have had a pair of erectus from OR (mustangs) for about six months. just recently, my male suddenly died withought warning. one day he was healthy, and eating and the next, he was liying in the sand dead. My female however is still alive, but Ive noticed she hasnt eaten in a long time! She never really ate much of what I fed them, but now she wont touch her food at all. I have a feeding station in which i put hikari mysis every day two times aday, and I have never seen her eat. I can even put it right in front of her and she acts like it dosnt exist. she is getting quite skinney, and I am worried. There is plenty of food in the tank without me feeding as I have TONS of large amphipods all over the glass,and copepods as well. But if she is eating them, why is she skinny? I dont know what to do. I have decided on upgrading my tank skimmer to an aqua C remora, and Im going to add more water flow as there is very little now. I am also going to get her another male Mustang. Will this help?
