Well, the whole feeding tube may be unnecessary after all because
SHE ATE TUNA!!! 
She did the normal turning her face away from the food and trying to bury the dish but I put a little of the broth on her lips. She seemed more interested then so I took some tuna and put it in front of her. She probably ate a good tablespoon or more!
Now I'm praying she will move on to other foods too.
