OP said before that it is a 210.
I weaned my old tire track eel (the one in my avatar) onto Hikari Cichlid Gold, but it took at least 3 months of trying and failing with various methods before he finally started accepting it. What ultimately worked for me was sort of a combination of several methods. I was primarily feeding him frozen krill at the time, so every night, I'd crush the pellets into smaller chunks and stuff them into about 2/3 of the krill (cut the head off, hollow it out a bit with scissors, and just push the pellet piece inside), and I would also soak whole pellets in the water with the krill while it defrosted, and since I was handfeeding my eel, I'd grab a handful of pellets and krill, and offer it all together, so he'd suck in the pellets along with everything else in my hand. I'm honestly not sure what part of that actually worked, but it did. After a while, I started just handfeeding him pellets alone, and then he started taking them from the surface as well.
I really miss that eel, he was an awesome fish. He died of a bacterial infection through what appeared to be a heater burn on his belly, and I couldn't save him. I had grown him from about 4" up to 20-22"over the course of 2-3 years. He died back in 2012, and I just bought a new tire track for the first time since then, a couple weeks ago. This one is about 4-5" right now, and he has been a handful so far. Despite every attempt to seal off the tank, he's managed to climb out 5 times now (luckily, I was around to grab it and put it back every time). I think I have finally solved this issue by wedging filter floss into every opening, blocking my HOB outputs with wire mesh, and weighing down the whole glass top. I haven't been able to get him to eat anything at all so far, either, though he doesn't look skinny yet. What's odd to me is that I never had any of these issues with my old eel.
