Few questions and Balfouris

[CyanideOwl]

I wanted to ask if anyone would be interested in my 3 Balfouris communal behaviours and their journey.

Also I want to ask about how the spider leg span is measured. Because it says for example T. Albopilosus is 15-17cm Leg span. Is it on spread out molt or is it when spider is sitting still because then the legs are longer but bent. I am asking because T. Albopilosus recommended minimal enclosure is 20x30 and when I draw a spider with 17cm leg span it seems like it would not fit inside the terrarium.

I know that Albo is not the most active and I cannot find the realistic photo of that spider inside that terrarium to see the proportions. I like to plan my terrariums long term and use proper sized cork bark and decor.

I wanted to either stack 2 glass terrarium 30x30x20 so I can have him in bigger one or just have him in 20x30x20 next to some bigger one.

I measure molts. So you are always slightly behind the curve, as you are measuring the old, smaller body.

But if a site says they go up to 17 cm do they mean spread out or just chilling sitting legs together.
Because 20x30x20 seems a little small for adult but also they are not the most active so it seems appropriate based on that. I'm not sure feels like 30x30 would be more proper?

Sorry, I have been away overnight. You measure their legs diagonally. So front left, rear right or the other way around. And it is with the legs laid flat. Molt's never really lay 100% flat. But you do get a good impression of size.

My Stirmi for example is well over 10 inches, but this is what her molt looks like before it's spread out.

So it would be rather small to put 17cm diagonal LS T. Albo in a 20x30. I will go with 30x30 then and stack the enclosures if I need to. It should hold right? 2 30x30x20 stack on top of each other.
