Arowana won't eat :[

[xionglue]

I have 2 arowana that i just bought from the local store. They fed it love glass worms and hikari sticks. One was sick from ammonia, which has been cured. I have tried feeding it those and also tried live feeder guppies. Eventually, one of them has denied them all. The other arowana is doing well and eating lots. Don't know whats wrong with him or is he sick. :[

hi dude what is your water parameters? Generally nh3 is harmful to live stock. If the other piece is eating it's a good sign, give the aro & yourself some good time before it starts eating again. Merry Christmas
