Hi, desprately need some advice on an arowana thats not eating well. Bought her back home 2 months ago but think she's has only eaten about 8-10 up to date. She is about 17"-18" and doesn't seem to have any external illness. Water parameter is fine. No amonia, nitrite or nitrate. Tempreture reading's fine. Ph level at 6.5-7.0. Even tried using the Tetra Arowana vitamin which is suppose to enhance appetide and health. A little bit of improvement, but still she doesn't eat well. She started eating quite consinstently last two week for about 4days continuously then just stop all of a sudden. She hasn't been eating for the past 1 and a half weeks. Can anyone help... don't know what to do?? Is it the environment?
