I've been reading the caresheet about them. I was just wondering that if a 20 gal is enough for 2 white's, and the 82 to 85 degree for daytime with the temp. drop down to about 72 is alright at night. Do they need to aestivate? Would they drown in a deep water water? So how deep the water bowl have to be? Are they hard to keep or easy? I want you guys' opinions on the humidity?
