i was told he was cb when i got him.. although he was my first panther i have owned many veileds/jacksons and never had a problem like that. also the fact that this decides to happen 2 1/2 years after i get him is strange too.. there was about a week or two that i got really lazy feeding him but then i always feel bad so i got him a live plant(ficus) and fed him regularly after that he really seemed fine until the last day.. poor guy
