Wow, Mo! I am sorry also to hear of this. But every sad story has great news within it also.
Here is a special fish that bonded with you, lasted 13 years(great achievement!), and probably knew as much about you in the fishroom as you knew about him!
Your experiences and photographs of Jumbo have inspired a generation of hobbyists and I am sure you have made this cichlid more popular! Congrats to your journey with Jumbo! I say celebrate the life he had and shared with you and mourn not! You have over a decade of great memories to share!
I will see you at the ACA Convention!
