I have had three haddoni. My first was a petco one and was in fair shape. It colored up good and grew quickly, by eating broken up prawns a couple times a week and it ate many snails, hermits and zapped my lawnmower blenny. It was a tank but I traded it and it's tank for my lobster tank. I got one from petco a month ago. It was bleached and floppy and had a gapping mouth. The manager gave it too me saying it was no longer for sale and a write off. It has made a great comeback and has regained most of it's color, tight mouth, and rigid body postures. I waited 3 1/2 weeks till it's first spot feeding. And I have a large 12" haddoni that has a very unique color. Lavender disc an yellow tips. It's a healthy one but I have lost many cleanup crews. I love haddoni's and can't wait to get a blue one.
