I am no expert... but I am very observant... so please dont take anything offensively...
funny cause i get contradicting info from everyone

the bowl wont fit in a smaller tank... neither will the hide
that whole plastic tub thing and racks arent my preference... and plastic is porous and smells overtime... im allegic to newspaper ink
they take advantage of every inch of this 55gal

I am very aware of separating them during feeding... they each have their own tub when I am cleaning the tank or for feeding

they have been living together since they were hatchlings.
they are not aggressive to each other or to me...i try to handle them about 3xs a week, at night or late afternoon, one at a time. i havent been struck or attempted to strike at all
I wont be separating them... if the conditions are correct, they do not show any signs of aggression towards each other, and they are not opposite sex (i am having them sexed after the move... I was told they were 2 females but i need to be reassured)... there is no need for me to disrupt them and separate them... i could see if they were unfamiliar with each other but they arent.
there are 2- 7ft boas housed together at a local store here
I have successfully had 2 baby corns in the same 20gal enclosure (they were together at the time of purchase so I bought 2)

and trust me... they bask.. on the left side of the hide i have a smaller hide that i used for corns, i put it in there to aid in the shedding of the smaller one... which didnt have any issues it came off fine... the bigger one came to me shedding or in the process of shedding.... but i havent taken it out cause they tend to lay their heads on the smaller hide right under a heat source... if u ask me thats basking

they hissed alot in the begining... the move here was very stressful, the previous owner had them in the tank during transport, the tank is heavy, and i am a wimp.. i havent heard a hiss in about 4 days

the substrate is covering the glass... about 1.5 inches almost 2.. and its like shredded papery fabric... and it holds moisture pretty well with low mold chance

I am thinking about a misting system, not sure yet

not that I don't appreciate the feedback
