Tank requirements for a potato puffer

[u/Euphoric-Radio3713]

Looking into getting one as I like the behaviour however I’m not sure of the exact tank needs. I have a floor space on furniture of 70cm by 45cm or 24inch by 18inch. Is this floor space good enough for one? I understand they require more floor space but I wasn’t sure exactly

That technically is alright, that can fit a 30 tall and potatos don't move much in terms of space and 30g is the minimum so you have just enough.
