Proud ocelot owner!
u can stil ask questions,she;s just looking for the best benafit of the animal
Definitely pursue the blood worms - mine tends to do fine, eating all the copepods in my tank, but when I put bloodworms in there, she seems interested. Adding a refugium, even a hang on back one, would really improve its chances of survival, as it would be a safe haven for the pods to reproduce and stock your tank.
With a tank that small it's a lot easier to overdose chemicals or upset the balance, so, especially if you don't need to, I'd shy away from it.
Also, if you have some good cave-like areas in your rock work, that will help, it'll give the mandarin a place to seek shelter when the damsel gets bitchy.
