am I overly concerned??

not realy sure where to put this but figured here would be ok.
my wife took in an iguana that is sick, possably with parasites.
the iguana doesnt bother me being in the same room as our BP's, but today she decided to put its tank next to one of the BP's tanks. Im afraid that if the iguana does happen to have parasites being so close to my BP some thing could possably find its way over to my BP.
am I just being paranoid about the whole thing? or is this a valad thought?

yes it is. i would move the iguana out of the room immediatly. then check your BP regularly for a while for mites and ticks. if you see him unusualy soaking he might have mites. after a while, and your sure the iguana has nothing and is healthy, you can put them in the same room.

if theres any confusion, i ment yes it is a valid thought

I'll agree with that just because mites are NOT fun (ask Genevive about this one)
