I'm so sorry for your loss...
I know how hard it is to say the final goodbye to a much beloved little friend, even more so when he was the first and the one who made you love and appreciate this species so much that led you into breeding.
I completely understand what you are going through, and you have my deepest sympathies.
You were very blessed to have Tango's company for 16 years, may the memories of all these years give you some comfort and help you heal.
Your precious boy will always live on in your heart.
Rest in peace, sweet Tango. You were much and will be missed.
