Since you have him separated, try to soak some pellet food in with bloodworms should increase the response towards other items. Not sure with fire eels but it helped with my wild Mastacembelus ellipsifer eel.
That's so true, I already restrict the amounts of massivore per feeding but I'm aiming to use 1 large bag of massivore for a month. Usually last less than a month but I supplement feedings with prawns and super worms.
PLJ is protruding lower jaw its when the aros lower jaw sticks out longer than the top. some varieties like reds tend to have it just like silvers are prone to drop eye but personally its not a big problem to me.
I plan to feed it a fair bit more to gain some size then it shouldn't be as...
The aro is eating massivore and carnivore sticks so i will do those as well as market prawns. I won't add too many other items if it's eating those, I will just feed constantly.
