I bought 3 last week to go in a1200 gal sys, bright green, blue, and one like yours from petco. Should have walked away from the green he said it came in the night before and he had already fed it a dead fish that morning. From what ive heard that is a nono, he was gone in 72 hrs the blue been hanging in there but his mouth hasnt look good from the day I got him though last night he moved to a more exceptable location and mouth was looking better. And the dang $30 haddoni from petco is trucking along looking good and eating. Myself all petco aint bad.
