Has this happend to anyone else before?

Hi all.
My Columbian Boa was sick a few weeks ago. It wasnt an R.I. but he did have mucas in his mouth and was weezeing a little. The vet gave me some drops and it seemed to clear things up. When he was sick his coloring went pretty dark. It has remained that way since. He used to have a lot of pink and grey, now he is dark grey and brown.
Have any of you heard of this happening before? Do you think him being sick caused his color change?

How long have you had him? And has he always been his previous color? If he is getting better after a prolonged illness he might well be coming back into his natural colors. That's a wild hazarded guess though and I don't want to misdirect you - I'll defer to Will or anyone else more knowledgeable in the Boa arena.

I've had him for just over a year. He is about 3-3.5' long. Im actually unsure of its sex. He has been light grey/pink for the entire time I've owned him up until he got sick...

Well then scrap everything i just proffered - was a hazarded guess. Hang out until someone who actually knows a good bit about them (or at least keeps them :P) comes along. Has ther been any change in diet/temps since he's been sick? eating less? tending to the cool hide etc?

when he was sick, I uped the temps a little, he has been hanging out on the cooler side of the tank though so I think I am going to drop them again...

CUSTOMER SERVICE NEEDED IN AISLE BCC POR FAVOR!!

(aside) Someone will be with you shortly - could I offer you a refreshing beverage in the meantime?

I do not have a specific answer to your situation, but I do know that some BCI's do change to a darker color while gravid, and retain darker tones after giving birth, so there is some evidence that physiological changes can change color. I have never heard of one changing color after recovering from an illness, however. Could it still be sick/recovering?

the sickness would definatly cause the color change. and my guess,like randy suggested, is that its probably still recovering, and maybe youll have to wait till the next shed for the colors to return. just a guess though. :)

mine gets darker about half-way between sheds. first 15 or so days, grey and pink as can be... with a beautiful red tinted tail. then the last 15 or so, he changes slowly to darker grey, (was in this stage when i bought him, hence the name...), and the pink is almost not visible. the tail is clearly brown, hardly any red.

Sounds like mouth rot by the way. Pretty common actually.
