The first one I had was very white and did not survive. It would not eat either. The second one was kind of light tan in color and it's been eating from day one what ever amount of PE mysis I give it. It has grow from a tiny 3'' to a 12'' in a year...and now it's dark brown except some part of it that does not receive much light and those are kind of light beige.
This is what mine looked like when I got it. Try to find one that at least has some trace of beige like mine and that is also eating: Also water quality is very important. 25 gallons is way too small for a sebae, as it will become 12'' and more. I feed mine each day, I rarely skip days.
And now here is the beauty, when it's fully inflated it's 12'' and more.
