80 baby garters, without going nuts? The short answer is you don't, but I do like a challenge. This is what I wound up doing and it seems to be working fairly well: Obviously catching enough worms the right size was out of the question, and I wanted them to start eating trout pieces, but they were not very interested. Decided to make a garter buffet. Took a trout fillet, froze it and used my razor saw (one of these thin Japanese saws) made some some 1-2 mm thick slices. Used a razor blade to make ~3mm strips, and then cut those crosswise to make a bunch of 2x2x3 mm chunks (easy when it's frozen). Then sliced up a nightcrawler into 2 mm segments (looked kinda like donuts) Put a bunch of the trout on a piece of paper and topped it off with nightcrawler pieces (including blood and guts), and kinda mixed it a little. Put it in the tank next to the hide, and lo and behold it worked, they chowed down on both the trout and worm pieces. Took hardly any time at all.
