image label gui not tweening?

my gui tween code isnt working? it runs the code but the gui not moving? here is the code:

if fishsuccess == true then
	fishrate.Visible = true
	fisharrow.Visible = true
	fisharrow.AnchorPoint = Vector2.new(0.5, 0.5)
	local arrowgoal = {}
	arrowgoal.Position = UDim2.new(0.2, 0, 0.019, 0)
	local arrowtweeninfo = TweenInfo.new (6, Enum.EasingStyle.Sine )
	TweenService:Create(fisharrow, arrowtweeninfo, arrowgoal)
			
end

*fish rate is another gui part that needs to be visible when the value is true

you didnt play the tween

if fishsuccess == true then
    fishrate.Visible = true
    fisharrow.Visible = true
    fisharrow.AnchorPoint = Vector2.new(0.5, 0.5)
    local arrowgoal = {}
    arrowgoal.Position = UDim2.new(0.2, 0, 0.019, 0)
    local arrowtweeninfo = TweenInfo.new (6, Enum.EasingStyle.Sine )
    TweenService:Create(fisharrow, arrowtweeninfo, arrowgoal):Play()
end
