What is a good size for a tank for 3 balfouris living together? I was thinking about 40x30 and 30cm tall would be enough since they will be close to each other.
For now they are around 2.5cm body length and they are in 20cm cube.

Safely put there recently they started to establish their nest

30x40x30 will be more than enough space for 3 adults, the 20cm cube you have them is fine until they at least double in size

Hmm... So would 30cm cube be fine as well? Then I can fit another big spider in next to them, since my shelf is around 65cm long. Not gonna lie it is hard to find 30x40 terrarium in normal price.
And yes I do not plan to move them any time soon. They are comfortable in there now.
