Yes, I'm from Thailand and once kept this lion.
That is Parapterios heterura
It's a kind of the coolwater fishes that do best kept in the temperature below 28 c.
Prone to skin infection and sensitive to low water quality and oxygen level.
When first acquired, it need some live food to started them feeding like some ghost shrimps, brine shrimps (in case the fish is not too big yet).
Some of my fish collection including this lionfish, Pterois miles.
