What a beautiful betta.
Just to let you know the plant he is in front of isnt a true water plant its a houseplant and will rot after a few weeks if not sooner.
Pretty fish. As for the plant., I have always heard that anything with varigated leaves was not an aquatic plant.
Edit: It's hard to tell about the decoration in the middle but if it has any sharp or rough edges on it, keep a close eye on Merlin as he may tear or rip his tail and fins.
