LionFish says.......
Well, now you're talkin' Lionfish is my name and well, lionfish are my game. Or something like that. Anyways, I have a Dwarf Lion at the time. Very cool fish. They are extremely hardy and long-lived. Good fish for any aggressive tank. Now, Fu Manchus are a little more sensitive than most lions. Lionfish are overall, one of the hardiest fish out to the hobby but Fu Manchus are just a little more sensitive. Just keep them well-fed with a varied diet and keep good water conditions and it should live for a good long time. And, yes, they will do very well together. Feed them foods like chopped squid, krill, shrimp, mussel, and silversides. Try to feed at least three of these to them at different times. If you have any more questions feel free to ask.
