Daytime humidity isn't a issue, can keep it at 49%- 50% no problem during the day but as soon as night time comes and I turned Michael's (whites tree frog) light off and it slowly climes to mid hight 60's to low 70's. His lights have been off for 2 hours and gone from 49% to 64% Is this something to worry about since its not at that level 24/7 as I know humidity has a tendency to rise at night anyway.

His exo terra is in the same room with a large aquarium and even though they are no where near each other, can the aquarium cause the increase in humidity? Plus he has a large water bowl as well which will obviously evaporate and add to it.

It doesn't seem to bother him though
