I ordered Betta channoides last winter. They arrived over a distance of 180km via specialized transport with heat pack in a Styrobox. Water temperature was around 16°C and both fish were dead. A heat pack seems useless to me if the transporter is not heated and the temperature is below 5°C… The transport company was “specialized” but the first question the driver told to me was: do fish really survive such transports?
Last Sunday I transported 8 Sphaerichtys selatanensis in my heated car in a “Kühltasche” cooling bag? without any problems over a distance of 400km.
I never use transport companies again to deliver fish!
