Do not feed the lion live fish though, you will be teaching him that behavior and he may become exited and "accidentally" eat the domino as well.
although this is true, i'm willing to bet the damsel is simply too big for the lion to eat at this point...the same reason my CB shrimp made it so long (almost a year now) yet my cleaner shrimp lasted about 3 weeks god rest his soul
