Blue Ribbon Eel feeding help

Hello everyone

after 3 months of waiting to receive my blue ribbon eel !! he arrived to my tank almost 2 weeks ago , while i was ready for a big challange of feeding him , i was armed with lots of people's history of strugeling to feed this amazing one . but still no succes till now .

he have his own tunnel under the sand bed , 3 exits and i placed a powerhead on the 4th to keep the water going through .

ok lets see , i tried so far live goobies , although my lion had them all i used the clipper with couple goppeis in , but he wasn't intrested !!! i did this couple times .

second atemp was krills , NOPE .

third was small peices of squid !! couple times but also nope.

he looks happy in the tank specially with his new home , but i don't want to see him died cause of starving !!!

so what tricks i can do to help him to eat ? or just keep trying what am doing ? any special food you think he will accept more ?? we don't have silverside ones here /

Thanks
