dwarf zebra lionfish , refuses to eat !

[darkreef]

Pretty sad iv trained my mandarin dragnet (male) to eat fiercely because of my poor attempts at feeding this fussy lionfish. And live food is out of the question! So any other advice would be great . Been four weeks since I got him and I can tell he's starting to get weak now. But he's still very active .

I swear he ate most of the brittle worms in my tank since I put him in there , I see a few when the tank was crawling . But they could of died off because I been hard on the water changes latley . And I don't have proof he did eat them just attacks the rocks for no reason sometimes .
