Hi - I have done numerous searches on and around FBT recommended temperatures. Generally, most of the recommendations say they are happy between 68 and 78 degrees. I have a 41 gallon aquarium (34x14x20) in a 1/2 land 1/2 water configuration. The land has live plants, 7 inches of hydroballs and stone (water flows under the land back to the waterfall pump and the chiller pump) 3 inches of ABG substrate, some moss, some cork, a stream and a waterfall as well as elevation changes. The water is about 5 inches deep with multiple live plants and some ghostwood... I am running the environment with a reef controller... I am tracking water temp, air temp, room temp, pH, and ORP. I've installed a mistking system, fogging system, seasonal moonlighting system, 2 chillers, and a 40W heater... all controlled with automation.

I wanted to provide a natural rise in temperature during the day and fall during the night. I used seasonal weather data from southeast asia for the temperatures... Aquarium sunrise is at 10am and sunset is around 10pm. The program takes the water and air temperature from about 78 degrees at 5pm to 70 degrees at 5am.

Here's my question: I am using the water temp to control the overall temperatures in the aquarium. The air temp seems to track pretty closely to the water temp. I'd like opinions on whether the temperature swing I am giving the frogs is beneficial or if it's too much?

They seem happy, but I'm not exactly sure how to tell if a FBT is happy. They eat all the crickets I give them - 15-20 every other day... or sometimes every day because everybody loves to watch them eat. All the FBTs eat one day or the next... None of them seem too fat... they all have clear eyes... they roam around from the land to the water... and overall seem pretty active.

Thoughts? The reason I am asking is because it occurs to me that in a normal outdoor environment, the air temp might get colder at night, but the water could stay pretty warm... or at least drag behind on the temperature drop. With my setup, both land and air are changing about 1 degree every 1.5 hours. While it's neat, it may not be what makes the frogs the happiest... So, I am looking for advice...

Thanks!
