I have a 80G with 10 pygos...I love it how they are more active but they peck at each other more. ATM I changed the thermostats to 72, never turn lights on, closed blinds, and had the ac on all day. It dropped to about 83F. I dont want to add frozen objects to my tank and scare my babies. Thanks for the advices guys! I feel bad for the bro in fresno, damn its way hotter there ! I am in long beach and I thought it was hot....slapped myself right now.
