Thought I was wrong once, but I was wrong about that...
:D
Im really sorry to hear about your BP. From what I've read, the IBD in BPs manifests itself and kills BPs MUCH faster than in boids, where it can lay dormant for years. Unfortunately there just isnt really a WHOLE TON of info available on the specifics IMO. I am going by what other keepers who have personally encountered IBD in their collections have shared with me...
I personally have never had to deal with IBD (Thank goodness) and I hope I never do.
