Something on my Clarkii

75gal with T12 daylight (48") T5 50/50 48" & T5 Actinic 48" - I had these same lights on my other 75gal until a couple months ago and in the other tank the seabe and bubble tip (which has now split) have done fine so I figure I'll do what I did for the other seabe and feed it ever 2 days or so for a month or two, however long it takes, until it gets some more color.

I do have a question about it though, some of the tips are pink, some are purple. Whats up with that? (My other seabe had purple tips which have now gone dark brown but it never had multi color)
