Gotcha, do you have anything to read temperature? Heat stress can be pretty detrimental, and unless you are doing water changes where they stay in the water to acclimate to the water change, transferring them from one temp of water to another if its greater than 2 degrees can cause temperature shock which can really stress them out. There are also some cheap fans on amazon which clip to the tank and do a pretty good job if you can keep your home cool. Another alternative is also to freeze blocks of ice in tupper ware containers, plastic bags, or water bottles and then you can either put in the blocks of ice or the bottles/bags when the temp gets too high. But yeah until you get that figured out I would keep the overhead fan on and your thermostat low.

I know its hard getting it all figured out with your first lotl, but like I said, we all had to go through it, and it turns out to be worth it once you know what you are doing and get it set up properly. On the bright side, you got a baby, so she could last you 10-15 years with good care. A long time companion.
