Your best bet in this case is to either have a predator tank, or a non predator tank. It can work with both of these however you need at least a 100 gallon and all fish need to be bigger than the lionfish. however accidents happen, lets say a tang swims to close and gets stung game over for the tang. Also even a predator tank is not safe for all predators, just be aware that friendly fish will live together 99% of the time and have no problems. Predators is a 50/50 , these fish eat other fish to survive, and if someone gets on each others nerves it's rumble in aquarium time and nothing good will come out of this.
For whatever its worth either make this tank a lionfish tank or a community tank. Also look forward to a bigger tank with a year or so if you choose the lionfish.
