you need to get all of the babies out of the aquariums and into mesh cages. they require heavy misting and keeping the air stagnent in the plastic/glass cages will cause URI.
i would be careful about turning up the heat on that ill baby. if you can't find crix in a local shop it is imperative that you order crix on line and have them airshipped immediately. they can't go w/out eating, as babies, and they have already had a rough start. big apple pet supply should be near you - or order from luck lure here in fl.
pm me if you need - i'm home all day
