Lionfish advice please

[reefwars]

In a small 34g all those dish would be dinner i had one for s bit in a small tank when I first started it's simply to small for a lion to swim and for others to hide the smaller the tank the better chance of grttin eaten especially the cardinals, even if its well fed in a small tank mouths cross paths too often to let a easy meal go by un noticed. My small lion ate three bangai's in one night
