LionFish says......
I sure think the lion would love that line-up of fish because he would have a smorgas board of food to inhale at his leisure. I usually don't recommend firefish, blennies, or gobys, or even six-line wrass with lionfish. You do realise that lionfish eat small fish and you do realise that all those fish in with that lion are small fish. Therefore, I would leave out the lion if you're going to have small fish. Also, scooter blennies are like mandarin dragonets. They feed primarily on copepods. They require a large, mature tank for them to be insured a full life. If you went with the firefish and the sixline wrasse you could do a lot in that tank but with the lion you can basically have a snowflake eel with it and you're done. And I want to clear one thing up for people who want to get Dwarf Lions. They are only dwarfs compared to other lions. They still get about 7 or 8 inches long. They really aren't Dwarfs at all. Skip the lion and you'll be alright.
