that sucks man, especially the GATF, but it doesnt surprise me with how skittish they are... once a dat is comfortable in a tank they can get nasty... i've got an 8 inch indo that badgers the other dats mostly, and also my gold dorado he hates, but he leaves my GATF's and VATF alone... thank god!!!! hopefully it stays that way... sorry for the loss, its not easy to get Goliaths that size, nor is it cheap
