Spiney eels are def different.. Sorry about the loss. But looking at the pictures he'd looked extreamely emmaciated. It's almost impossible to bring them back. Miki, Try live black worms at that size, ghost shrimp, or nightcrawlers/earthworms chopped up into sizable peices. let them sink infront of where he hides when you turn the light off for the night. btw the TSN will eat him once he figures out how too, Big cats do not make suitable tank-mates... Ever. And Cichlids are also usually to aggressive. I would suggest moveing the other fish and leaving the fire in the tank by itself until you get it eatting. THen adding other tank-mates.
