I'd say he's around 2ft in length give or take. He is quite the gentle beast, I've been hand feeding him since day one. Raised him from a baby of 2".
This winter I upgraded from (3) 300 watt heaters in the sump to a 2KW inline jacuzzi heater w/ a thermostatic switch. Temps are easier to keep stable and the electric bill is actually less because the "on" time is less now than with the three smaller heaters.
