Snake Food

[Serpico]

My two garters, but some say they are actually ribbon, eat salmon, trout, atherina boyeri (small fish F/T or fresh). Refused pinkies, whole or parts, refused guppies. Not yet offered nightcrawlers due to unavailability in my country atm.
My old couple, who were surely sirtalis sirtalis, ate all the above save pinkies, plus veal and beef meat stripes, especially heart, plus any kind of worms (most probably they got some red wrigglers too), plus toads, frogs and tadpoles (the latter three, captured in the lake). Interesting to say, thy never ever got problems, of any kind.

big females can swallow and digest baby-chicks,
but need high temperatures for it.

My big females are all on rat pinks. I feed my adult males mouse pinks. babies chopped fish and ground up reptomin.

The most interesting one, food wise is the Hierophis (see "warning, snake at large" thread) Viridiflavus, corresponding specie of your Whip snake, i think, who eats lizards and small birds, when wild, and who now eats the two garters's leftovers, especially the small FT fish atherina boyeri (sort of big guppy, bought at the local fish market).... now you tell me WHERE, in the wilderness, he has ever seen a fish????
