Recently (2 weeks ago) I got a green bubble tip about 5 inches in diameter. He started on a rock in the middle of my tank, but over the past week and a half he has moved 4 or 5 times, and is now in a dark corner. He has been there for a few days and seems happy (good color, fill, poofyness). He has a maroon clown that hosts him. My main question is, with 4x54 T5 why is he looking for a dark corner? And by dark I mean DARK, it is hard to see him! He ate some krill today and seems fine but I am just making sure that he will do okay there as I am under the impression that they need quite a bit of light. Thanks!
