Why surprised, that it grows warm? I supposed you yourself put it in the warm tank?I'm surprised it grows warm as well as in the cool tank (where Octopuses is). I'll call this one Squiggy.
A satisfactory conclusion! Somebody in North Queensland (not me hehehe) says it grows well in North Queensland. Tropical conditions here.I think, we can conclude, that it's either a very adaptable species or that it can grow within a wide temperature range!
