I just got one. Yes I know I have a full reef aquarium but I have allways wanted one of these and am keeping an eye on it. But I need to know everything about it to take care of it. It is night time and I have noticed that the bubble tips are gone there just kinda straight like normal enenomy tenticals. What goes this mean. Bad... Good. Also what about feeding it. Just anything else about it I might not know. Thank u very much everyone
