I have been trying to get them to eat NLS but they only eat shrimp stuffed with pellets. I tried the superworms and my fish got super fat and wouldn't eat anything else. Xb used to be a great eater until I used superworms. SR will eat hikari pellets but they are no longer avail. in Cananda, and I'm almost out, so I have to try to get him on something else. Shrimp is the only thing they'll both eat.
