I feel like they are same as arowana. as The arowana grows older, the amout you feed should be MORE but in longer periods of time. for ex. From young i fed mine crickets every day. till about 12 inches started feeding it every 3-4. and now its close to 18, just about every 4-5. This may be the same as The endi. I have a common senegal and its only about 5 inches. so i am not at that point yet.
