Lion fish?

[OUfishman]

I was wondering if it would be at all possible to have a lion fish (any type) in a 20 long? Could it be happy in a tank that small and by itself?

IMO, Yes, fuzzy dwarf, Fu Manchu, Miles, Dwarf Lionfish are the smallest and the best for smaller tanks. However be careful with the Fu Manchu, it is hard to get on frozen food.
