Try feeding your achilles some gracillaria if you want to try to fatten him up

when you go look at him and he is grey could he just have woken up? I had mine for almost 3 years before I sold him when I took down the tank, when he slept he went molted, and soon after waking up he was full color. he didn't know I could see his hiding spot :mrgreen: Could be a defense/cammo to help him hide when he sleeps.
