A few days ago I collected a young male valley garter (T s fitchi).
Today I offered him a live pinky, which he refused, and some goldfish - he took some of them.
I know about the goldfish issue, that they should only be occasionally be offered - I'm actually hoping to get him onto f/t rodents and bait shop minnows, I need to shop around the bait shops and see who carries them. I also may offer Pacific treefrogs (P regilla) when in season, but I can only collect two at a time (bag limit) and I'm not sure I'm allowed to collect two at a time for an eternity. I know where I can get some bullfrog tadpoles (no bag limit, invasive species) but they aren't in season there yet.
Anywhoo - I currently have him in a 20 gallon with aspen on warm side (heated with thermostat regulated UTH to 80F substrate), and a large water dish surrounded by moss on cool side (I mist the moss lightly when feels dry), plan is to change water every two days or when he defecates in it.
Anything else I need to consider? It's been years since I've kept garters, and while I have kept the species - never this subspecies (I had a california red-sided and an eastern growing up). It seems this subspecies doesn't get as large as Cal red-sided or easterns, but I guess we'll see. I know the large garters I had regardless of species were easy to get onto rodents (usually just take 'em, sometimes a fish or frog scenting was needed once or twice) but this guy isn't large, I'd guess maybe 18 inches.

Not as spectacular as the California Red-Sided - but I'm not going into their range anytime soon, and I've not kept this subspecies before.
Thanks for any tips
