My green aro had stopped eating for a couple weeks and just lately has started to eat the occasional mealworm. He used to eat like a pig so I hope he returns to his former self soon. My water parameters are all zero but he is in a planted 6' tank where the plants fill half the tank, so he may need more room as well. He is only about 8", though, so the tank should be a good size for him. Up your wc and he should come around in time.
arowana are known to fast from time to time..so do not panic.. keep trying everyday but take out all uneaten foods so they do not contaminate the tank.. they can go along time with out eating.. maybe you should try meal worms ... sometimes that will stimulate his appetite.. i never feed live except when a fish is fasting.. it is worth a try...
thats what i think he is doing . i will give him a try with some live feeders tomorrow . and i will up my do biger wc to . cheers guys i will let you know how i get on .
