Ornate bichir does not seem to be eating

[batang_mcdo]

Its been a while since I last saw my female ornat ebichir eat something.
My ornate is about 12 inches, She's been with my arowana, 2 tinfoils and a flagtail in my tank for a few months.
There used to be 3 of them, I sold off the 2 males, from the start this piece already has been more shy than the 2 males which would even go to the tanks surface to eat.

i feed my Arowanas with prawn and fish. I think its been a while since i saw here last eat a piece of fish?
The fish looks normal? meaning it looks healthy, but I'm wondering if she gets anything to eat? as I have not seen here eat for a while?.

Any advise?
tank is 4x2x2 with 75 gallon sump which has been running for years?
I do 20 - 30% weekly water change.

i have a 5 inch ornate that has the same problem but what my ornate will do is it will wait till everyone is gone then come for the scrapes. some times it'll just wait a couple days then eat right away. what i do is i turn my lights off for about 5 minutes so that the bichirs can have a head start at the food then after that i will turn the lights on so i can inspect my fishy friends to make sure they are ok and nothing is wrong.
