okay my aro has been acting a bit different for the past 3 weeks. i usually feed him twice a day ( pallets) and every so often i feed him feeders. i qurentine the feeders for at least 3 weeks. but now he wont accept anything. not even feeders which are his favorite. i know hes hungry cuz he will snap at my hand when i open the lid. but when food hits the water he will ignore it. his tankmates go crazy when i feed them. im a bit concern about his loss of appetite, cuz i have had him for at least 6 months and never had this problem. what can it be???
