What would hyou add first to the tank. Currently a 75 with a YT and maroon clown. Potters angel, potters wrasse, or 4 line. My concern is I just swapped over tanks about a month ago. Not sure on the pod pop. I used the same LR and it is still covered with life. Sand is all new....I'm inclined to go for the 4 line. Since I am reasonably sure I can get him to eat. Where as both Potter's will require training. I'm just wondering if the pod worm pop will be large enough for them to eat till they get on frozen....
