Sorry for your loss-that was a beautiful fish- I once lost a 14 inch Trimac-to this day I will never know how it died.
I know this sounds crazy but any fish that I have had for more than 2 years and atleast a foot I take to a taxidermist and have them mounted in my living room-I got Trimac, RD, Buttikefori, Escondido, Barred Midas-it's like there right there with me-LOL
