the options here suck, pet smart or pet sense, or an outrageously expensive independent store. none of them sell feeder minnows, just little tetras, which would work, i guess. crickets aren't a good choice for the turtles, mine are aquatic (yellow belly sliders) and the crickets would just drown and make a mess. they do eat meal worms, i give them a couple of live ones, a few canned ones, a little kale every day, some mango or apple once a week, and pelletized food with vitamins. the lizard eats crickets though, but i don't want to raise them, they stink, and i don't want a big tank of them stinking up the house. 50 a week for 8 bucks is just fine.
wax worms are ok, but they're really high in fat, should be like a once in a while treat
