I think I made all of them.
Bought an assist feeder import from a store I shouldn't have. Tried aquarium gravel as a substrate with an unregulated heat mat inside the tank and a light bulb on a mesh topped tank ( guarded at least ) to provide the hot end. Housed multiple snakes in one huge viv (with a ceramic on a thermostat ) and not a thought of quarantine when I got more, knew nothing about humidity or accurate temps.
Joined here and got schooled - and it turned out to be the best thing ever for my snakes. Though I acted a bit butt-hurt at first.
